LIFE OF ARJAV

Practical AI, systems, skills, learning workflows, and useful resources for people who want to keep building.

Instagram: @lifeofarjav

The short version

You do not need another giant list of “500 free courses.”

You need a small set of reliable places that cover different jobs:

Learn practical AI: OpenAI Academy
Study structured courses from IITs / IISc: NPTEL + SWAYAM
Go deep with university-level material: MIT OpenCourseWare
Discover free courses, books, films, and language resources: Open Culture
Research old books, websites, media, and primary sources: Internet Archive
Build a better reading and thinking habit: Postcards by Elle
Learn how to become a cross-disciplinary learner: Odysseas

This guide explains what each resource actually is, who can use it, what is genuinely free, where the catches are, and how to use it without becoming a course collector.

Accuracy note

“Free” does not mean every feature on every platform is free.

NPTEL learning is free, but an optional certification exam usually costs money.

MIT OpenCourseWare is free, but it does not issue certificates or academic credit.

Open Culture is primarily a curator that links to resources hosted elsewhere.

Internet Archive has free access, but some books use timed library-style borrowing.

Postcards by Elle has both free and paid posts.

Odysseas is a free YouTube learning resource, not a formal course platform.

Last researched and verified: 7 August 2026.

1. OpenAI Academy

Official website:
https://academy.openai.com/

Courses:
https://academy.openai.com/pages/courses

AI Foundations:
https://academy.openai.com/public/courses/ai-foundations-juzjs?autoEnroll=true

Codex for Beginners:
https://academy.openai.com/en/public/videos/codex-for-beginners-2026-04-22

What it is

OpenAI Academy is OpenAI's public learning platform for developing practical AI skills.

It includes:

structured courses
live and on-demand events
practical resources
community groups
role-specific learning
beginner-to-advanced material
AI workflow and agent training
Codex and builder content

OpenAI states that Academy sign-up is free and open to all. Some specialized community groups may have separate invitation or referral requirements.

Who is eligible?

General Academy access: open to everyone.

For the AI Foundations course specifically:

no technical background is required
it is designed for people new to AI or those who want stronger fundamentals
you need a ChatGPT account
the course recommends bringing a real work task to practise on

This makes it useful for:

students
founders
operators
marketers
creators
freelancers
managers
non-technical professionals
developers who want a cleaner foundation

What should you start with?

If you are completely new

Start with:

AI Foundations
Applied AI Foundations
Agents and Workflows

The current AI Foundations course is approximately 70 minutes, self-paced, and provides a course-completion certificate after completion.

If you already use ChatGPT regularly

Skip random prompt tutorials and focus on:

Applied AI Foundations
Agents and Workflows
workflow design
review checkpoints
reusable instructions
agent boundaries
evaluation habits

If you build software

Add:

Codex for Beginners
Codex Bootcamp resources
builder events
API / agent sessions

The right way to use OpenAI Academy

Do not treat it like Netflix.

For every module, bring one real task from your work.

Examples:

turn a recurring report into an AI-assisted workflow
improve a research process
create a content review system
build an SOP generator
create an internal knowledge assistant
automate a repetitive analysis task

A simple learning loop

Watch one module.
Apply it to your own task immediately.
Save the prompt or workflow that worked.
Note where the model failed.
Add review rules.
Repeat the process until the workflow is reliable enough to reuse.

The real skill is not “prompting.”

It is learning to create repeatable AI-assisted work.

What the certificate means

Treat the Academy certificate as a course-completion credential, not a university degree, professional license, or proof that you can independently build production AI systems.

The strongest proof is still:

course + project + explanation of what you built

Best use case

Best for: practical AI literacy and turning AI from a chatbot into a repeatable work system.

2. NPTEL + SWAYAM

NPTEL:
https://nptel.ac.in/

NPTEL online courses:
https://onlinecourses.nptel.ac.in/

SWAYAM:
https://swayam.gov.in/

NPTEL on SWAYAM:
https://swayam.gov.in/nc_details/NPTEL

What it is

NPTEL is an Indian online learning initiative built around courses created by faculty from IITs, IISc, and other participating institutions.

NPTEL courses commonly run for:

4 weeks
8 weeks
12 weeks

Courses can include:

recorded lectures
weekly assignments
discussion forums
teaching-assistant support
faculty interaction
optional certification exams

SWAYAM is the Government of India learning platform through which NPTEL and other national coordinators offer online courses.

Who is eligible?

SWAYAM's current FAQ says:

any person in the world can register
there is no general age or eligibility requirement for joining online courses
individual instructors may recommend prerequisite knowledge
anyone may join an online course and register for an exam, subject to the course's rules

If you are outside India and want certification, check the current exam instructions for that specific course and national coordinator because examination arrangements can differ by location.

What is actually free?

Free

course enrollment
lectures
learning material
weekly learning experience
assignments and self-testing
discussion access where available

Usually paid

The optional NPTEL certification exam is generally listed at ₹1,000 per course exam on NPTEL's official information pages.

Do not pay for an exam unless you actually need the certificate.

How certification works

For most NPTEL courses, the published general pass rule is:

average assignment score: at least 40/100
final exam score: at least 40/100

However, NPTEL explicitly notes that course-specific criteria can differ, particularly for certain programming or discipline-specific courses.

Always read the actual course page.

Certificates are generally issued as e-verifiable digital certificates.

Important timing rule

Unlike MIT OpenCourseWare, many NPTEL certification courses operate on a schedule.

A course may have separate dates for:

enrollment
course start
assignment deadlines
exam registration
exam date

As of August 2026, the July–December 2026 NPTEL semester is underway, but each course has its own timeline.

Do not assume you can join every certification course at any point in the semester.

The right way to use NPTEL

NPTEL works best when you want discipline.

Use this workflow

Pick one course aligned to a real skill you want.
Check prerequisites before enrolling.
Put assignment deadlines on your calendar.
Watch lectures at 1×–1.5× rather than racing through them.
Attempt the assignment before looking for explanations.
Keep a “mistake log” for questions you got wrong.
Build a small project or summary around the course.
Take the exam only if the certificate has value for your goal.

Who should prioritize the certificate?

A certificate is more useful if you are:

a student who can potentially use it for credit transfer
a job seeker who needs structured proof of coursework
an employee documenting continuing education
applying to a role where the subject is directly relevant

It is less useful if you are only taking the course for curiosity.

Best use case

Best for: people who want IIT/IISc-quality structured learning with deadlines, assignments, and an optional verified credential.

3. MIT OpenCourseWare

Main website:
https://ocw.mit.edu/

MIT Learn:
https://learn.mit.edu/

Course shown in the carousel: How to AI (Almost) Anything:
https://ocw.mit.edu/courses/mas-s60-how-to-ai-almost-anything-spring-2025/

What it is

MIT OpenCourseWare, commonly called MIT OCW, publishes learning materials from thousands of MIT courses across the institute's curriculum.

MIT says OCW is:

free
open
self-paced
available without enrollment
available without creating an account
available without start or end dates

Depending on the course, materials can include:

syllabus
lecture notes
readings
assignments
exams
solutions
videos
textbooks
faculty insights

Not every course contains every type of material.

Who is eligible?

Anyone.

You do not need to:

be an MIT student
apply
enroll
create an account
meet a formal age requirement
live in the United States

Important limitation

MIT OpenCourseWare does not provide academic credit or certificates for using OCW.

If your primary goal is a credential, choose a different learning product such as an eligible MITx offering or another structured certificate program.

The AI course shown in the carousel

How to AI (Almost) Anything

The Spring 2025 course is taught by Prof. Paul Liang through MIT's Media Arts and Sciences.

The course focuses on:

modern AI
deep learning
foundation models
multimodal AI
language
vision
audio
sensors
real-world data modalities
AI research thinking

The published OCW version includes learning resources such as:

lecture notes
readings
written assignments

It is marked as a graduate-level course.

That means it is free to access, but “free” does not mean “easy.”

The right way to use MIT OCW

Do not browse twenty courses in one sitting.

Pick one.

Then recreate the discipline of a real semester.

Recommended workflow

Read the syllabus first.
Write down prerequisite gaps.
Create a weekly study schedule.
Read/watch the assigned material.
Attempt the problems before checking solutions.
Summarize every module in your own words.
Build one project or essay from the course.
Publish your notes or project if appropriate.

A useful rule

If you spend:

70% consuming
30% solving/building

you are probably still too passive.

For technical courses, reverse that over time.

Best use case

Best for: people who care more about deep learning and university-level material than certificates.

4. Open Culture

Main website:
https://www.openculture.com/

Free online courses:
https://www.openculture.com/freeonlinecourses

Free language lessons:
https://www.openculture.com/freelanguagelessons

What it is

Open Culture is not one giant university.

It is a curation layer for free educational and cultural material across the web.

Open Culture says its mission is to centralize high-quality educational media that would otherwise be scattered across the internet.

Its current site lists collections including approximately:

1,700 free online courses
1,150 free movies
1,000 free audiobooks
800 free eBooks
200 free textbooks
300 free language lessons
podcasts and other cultural resources

These figures can change as the catalog changes.

Who is eligible?

Open Culture itself is broadly accessible on the web.

However, it often links you to external providers.

That means the final destination may have its own:

login requirements
region restrictions
enrollment windows
certificate fees
licensing restrictions
account requirements

The most important thing to understand

Open Culture is primarily a discovery engine, not the creator of most courses it lists.

It does not issue one universal “Open Culture certificate.”

If a course offers a certificate, the rules come from the actual course provider.

The right way to use Open Culture

Do not scroll endlessly.

Use it like a librarian.

Example

Suppose you want to learn behavioral economics.

Search Open Culture for economics resources.
Pick one structured university course.
Pick one book or audiobook.
Add one documentary or lecture series.
Ignore the rest for 30 days.
Create one set of notes or one project from what you learn.

Open Culture becomes powerful when you use it to build a small syllabus, not a giant bookmark folder.

Best for

broad intellectual exploration
discovering older university courses
films and documentaries
classic books
audiobooks
language learning
humanities
philosophy
history
literature

Best use case

Best for: curious people who know the subject they want to explore but do not know where the best free material lives.

5. Internet Archive

Main website:
https://archive.org/

Wayback Machine:
https://web.archive.org/

Internet Archive Scholar:
https://scholar.archive.org/

Open Library:
https://openlibrary.org/

What it is

Internet Archive is a nonprofit digital library.

It provides access to an enormous range of material, including:

books
texts
films
music
old radio
software
archived websites
research papers
historical media

The Wayback Machine allows you to view archived versions of websites from the past.

Internet Archive Scholar is a separate search experience for academic papers and research articles.

Who is eligible?

Anyone can browse public material.

An account is not necessary for every item.

However, a free account is required for borrowing books that use Internet Archive's lending system and for activities such as uploading.

How book access actually works

Internet Archive's help documentation currently describes several states:

“Read”

The item can be read or downloaded immediately where available.

No borrowing account may be required for unrestricted material.

“Borrow for 1 hour”

requires a free account
generally read through the online BookReader
can often be borrowed again if a copy is available

“Borrow for 14 days”

requires a free account
can be read in BookReader
some books can be downloaded as an encrypted eBook
compatible LCP readers may be required

“Join Waitlist”

Used when eligible 14-day loan copies are already checked out.

The system can notify you when a copy becomes available.

Internet Archive says a user can borrow up to 10 books at a time, and loans return automatically, so there are no late fees.

Do not make this mistake

Do not assume:

“If it is on Internet Archive, it is automatically public domain.”

Availability, downloading, borrowing, reuse, and licensing can vary by item.

Check the rights and license information.

The Wayback Machine is a research superpower

Use it when you want to:

see how a company positioned itself years ago
recover an old article or webpage
study historical website design
compare old product pricing
research how a market evolved
find deleted documentation
verify what a page used to say

Save Page Now

The Wayback Machine also lets you submit a live URL to create an archived snapshot.

Useful for:

research evidence
citations
preserving important pages
documenting changes

The right way to use Internet Archive

Search with intent.

Instead of typing a broad word like marketing, search for:

a specific title
an author
a company
a historical period
an old software product
a specific URL in Wayback Machine
a known document or paper

The value comes from primary and older material you will not find in a normal feed.

Best use case

Best for: research, historical material, forgotten books, old websites, primary sources, media archives, and internet history.

6. Postcards by Elle

Newsletter:
https://postcardsbyelle.substack.com/

Start here: “how to get smart again”
https://postcardsbyelle.substack.com/p/how-to-get-smart-again

What it is

Postcards by Elle is a Substack publication by Elle focused on:

curated recommendations
“brain food”
books
essays
films
media
long-form writing
reflection
intentional learning

The publication describes itself as:

curated recommendations, brain food, and longform essays

It also publishes weekly postcard-style issues.

Who is eligible?

There are no formal learning prerequisites.

You can read publicly available posts on the web.

The newsletter supports both:

free subscribers
paid subscribers

Some posts are fully public while other pieces are reserved for paid subscribers.

The best starting point

The post “how to get smart again” is a useful entry point because it focuses on:

rebuilding attention
becoming more intentional about media
reading and watching with more thought
intellectual curiosity
remembering and reflecting on what you consume

The author explicitly notes that some later posts in the broader series are for paid subscribers.

What this resource is not

It is not:

a university course
a certification program
a peer-reviewed academic database
a replacement for primary research

It is better understood as a curated intellectual newsletter and personal learning companion.

The right way to use it

Use it to build taste and curiosity.

Try this weekly system

Read one newsletter or essay.
Save only 1–3 recommendations.
Choose one book, article, film, lecture, or essay.
Write five lines about what you learned.
Record one idea that changed your mind.
Share or discuss one insight with someone.

This prevents recommendation overload.

Best use case

Best for: people who want to read more thoughtfully, improve their attention, discover books and essays, and build a richer intellectual life.

7. Odysseas: How to Become a Polymath

Video:
https://www.youtube.com/watch?v=5f7ZRAmueOM

What it is

This is not a course platform.

It is a specific free YouTube learning resource from Odysseas titled:

How to Become a Polymath (full guide)

The video was published in February 2026 and is approximately 21 minutes long.

Its chapter structure covers:

what polymathy is
why polymathy matters
choosing subjects
how to learn
building a system
finding a project

Who is eligible?

Anyone who can access YouTube can watch the public video.

No academic background is required.

There is no certificate.

The video description may also include creator promotions or sponsorship links. Those are separate from the free video itself.

Why this belongs in the list

The other resources give you material.

This one is useful because it forces you to think about how your interests connect.

The internet makes it easy to learn:

code
finance
history
AI
design
writing
psychology
philosophy

The difficult part is turning scattered interests into a coherent learning system.

The wrong way to become a “polymath”

Do not:

collect random courses
switch topics every two days
confuse curiosity with competence
watch videos without producing anything
start six skills at once
chase the identity of being “multi-disciplinary”

A better approach

Choose:

1 core skill

Something directly useful to your work or career.

Example: software engineering.

1 adjacent skill

Something that multiplies the core skill.

Example: AI automation.

1 expressive skill

Something that helps you communicate or distribute your work.

Example: writing or content creation.

Then build projects that force the three to overlap.

That is more useful than trying to “master everything.”

Best use case

Best for: people with many interests who need a system for turning curiosity into real capability.

Which one should you use?

If you are a student

Start with:

NPTEL
MIT OpenCourseWare
OpenAI Academy

Why:

structure
assignments
strong academic material
practical AI skills
optional credentials where relevant

If you are trying to get hired

Use:

NPTEL for structured subject knowledge
OpenAI Academy for practical AI workflows
MIT OCW for depth
build a project that proves what you learned

Do not rely only on certificates.

A stronger portfolio entry looks like:

Completed a structured course in X, then built Y using the concepts, measured Z result, and documented the architecture / process.

If you are a founder or operator

Prioritize:

OpenAI Academy
MIT OCW
Open Culture
Internet Archive

Use structured learning for skills and archival resources for:

market research
old landing pages
positioning analysis
historical category research
technical understanding

If you are a creator

Use:

Open Culture
Internet Archive
Postcards by Elle
MIT OCW
OpenAI Academy

The goal is to stop creating from the same feeds as everyone else.

Go deeper into:

primary sources
books
old lectures
archived websites
unusual disciplines
research
long-form writing

That is where original content angles usually come from.

The Life of Arjav learning system

The biggest mistake with free learning is trying to consume too much.

Use this instead.

Step 1: Pick one outcome

Bad:

I want to learn AI.

Better:

I want to build an AI support agent that answers questions from company documents.

Step 2: Choose one anchor resource

For structured learning:

OpenAI Academy
NPTEL
MIT OCW

Pick one, not all three at once.

Step 3: Add one discovery resource

Use one of:

Open Culture
Internet Archive
Postcards by Elle

This gives you broader context without replacing your main curriculum.

Step 4: Create something every week

Examples:

a small app
an essay
a workflow
a research memo
a GitHub project
a dashboard
a public case study
a tutorial
a set of notes
a presentation
an automation

Learning sticks when it has an output.

Step 5: Keep a proof-of-work folder

For every topic, save:

what you learned
what you built
screenshots
GitHub links
demos
notes
mistakes
results
before/after examples

After a few months, you do not just have “knowledge.”

You have evidence.

A simple 30-day plan

Week 1: Build foundations

Choose one:

OpenAI Academy AI Foundations
an NPTEL introductory course
an MIT OCW introductory course

Goal: understand the core concepts.

Week 2: Apply

Build one small project from what you learned.

Keep the scope small enough to finish.

Week 3: Expand your inputs

Use:

Open Culture
Internet Archive
Postcards by Elle

Find three sources outside your normal feed.

Goal: add context, history, and better ideas.

Week 4: Synthesize

Create one public or private artifact:

project
tutorial
guide
essay
case study
presentation

Then write:

What did I learn?
What did I build?
What failed?
What would I do differently?
What do I want to learn next?

My recommended rule

One course. One project. One public proof. Then move on.

Free education becomes valuable only when you turn it into:

knowledge → skill → proof → opportunity
