Best Free Websites & Apps for NEET & JEE Preparation

You do not need expensive coaching to crack NEET or JEE. In 2027 there are enough high-quality free resources to cover the entire syllabus, test yourself, clear doubts and revise - if you know which ones to use and how to combine them. Here is the honest, no-fluff list of the best free websites and apps, and exactly what each is good for.

The rule: fewer tools, used properly

The biggest mistake students make is collecting dozens of apps and studying from none. You need just four things: your textbook, one notes-and-tests site, one AI tutor for doubts, and a revision system. Everything below fits one of those roles. Pick one per role and start today.

1. NCERT textbooks (the non-negotiable base)

Free official PDFs, and the single most important resource for NEET - around 85-90% of NEET questions come straight from NCERT lines. For JEE, NCERT is the foundation you build problem-solving on top of. Read every line, table and diagram. Everything else on this list supports NCERT; nothing replaces it.

2. Zaymiey - free notes, tests, mocks & an AI tutor

Zaymiey is 100% free (no payment of any kind) and covers all 126 NCERT chapters for Class 11, 12, NEET and JEE:

  • Three-tier notes with labelled diagrams - Key Points, Full Notes, and Advanced NEET/JEE content, for Biology, Physics, Chemistry and Math.
  • Chapterwise tests at three levels and full NEET-style mock exams with an All-India-Rank estimate - start practising free.
  • An AI tutor for instant doubt-clearing, and swipeable Study Reels for quick revision.

The workflow that works: read a chapter's notes, take its chapterwise test the same day, and revise with reels before bed.

3. Khan Academy - free video concepts

Free, ad-free video lessons that build concepts from scratch. Best for Maths and Physics when a topic is not clicking from text alone. Watch the concept, then immediately test yourself - do not let video-watching become passive.

4. PhET, Desmos & GeoGebra - see it, do not just read it

PhET Interactive Simulations (free) let you play with physics and chemistry - projectile motion, circuits, gas laws - so abstract ideas become obvious. Desmos and GeoGebra (free) let you graph functions, trig and conics live. For visual learners these turn the hardest Maths and Physics topics into something you can actually see.

5. A free AI tutor + Anki for revision

A free AI tutor (ChatGPT, Gemini or Claude) is your 24/7 doubt-solver - ask it to explain concepts, quiz you, and summarise chapters (always verify facts against NCERT). See our full AI study guide and prompt list. For raw memory - formulas, reactions, biology facts - Anki (free) uses spaced repetition so you revise exactly when you are about to forget.

How to combine them (a simple free stack)

Learn from NCERT + Khan Academy videos. Understand & revise with Zaymiey notes, reels and an AI tutor. Practise with Zaymiey chapterwise tests and mocks. See the hard topics on PhET/Desmos. Memorise with Anki. That is a complete, genuinely free prep setup - no coaching fees.

Frequently Asked Questions

Can I crack NEET or JEE with only free resources?
Yes. Free NCERT textbooks plus a free notes-and-tests site like Zaymiey, free videos (Khan Academy), free simulations (PhET), a free AI tutor and free flashcards (Anki) cover the whole syllabus, testing and revision. What matters is consistency and active recall, not how much you pay.
What is the best free website for NEET preparation?
For NEET specifically, start with NCERT (official, free) for theory and Zaymiey (free) for NCERT-aligned notes with diagrams, chapterwise tests, full mock exams with a rank estimate, and an AI tutor. Add Khan Academy for video concepts and Anki for memory.
Are there free mock tests for NEET?
Yes. Zaymiey offers free NEET-style full mock tests with an All-India-Rank estimate, plus chapterwise tests at three difficulty levels for every chapter. Taking timed mocks and reviewing every mistake is one of the highest-value free things you can do.
Do I need paid coaching for NEET or JEE?
No - coaching can help with structure and doubt-solving, but it is not required. Many students crack NEET and JEE with NCERT, free online resources and discipline. Free tools now cover notes, tests, doubts and revision; the deciding factor is consistent self-study, not fees.
Which free app is best for last-minute NEET revision?
Use spaced-repetition flashcards (Anki) for facts and formulas, and quick-revision formats like Zaymiey Study Reels for bite-sized recall. Pair them with an AI tutor asking you the 20 most likely facts from each weak chapter.
