JEE and NEET preparation tips you can act on this week

Every article here answers one question a student actually asked — how to analyse a mock, what changed in the syllabus, how many marks a chapter is worth — and ends with something to do tonight. BrainStride is an AI tutor for JEE, NEET and Olympiad preparation that runs a 20-minute diagnostic, maps your weak chapters and writes a daily plan, with every solution checked by teachers.

About the BrainStride blog

Who writes the BrainStride blog?

The BrainStride Exam Desk drafts every article with AI assistance, checks each fact against the official source cited on the page, and a subject teacher reviews it before publication. Exam facts carry the year they belong to, and anything not yet officially announced for 2027 is labelled expected. The editorial policy page explains the full review process.

How often is the BrainStride blog updated?

Articles are reviewed whenever an official notice changes something they cover — a new information bulletin, a revised date, a published cutoff or answer key — and at least once every exam cycle. The Updated date at the top of each article shows when it was last reviewed, so you can tell at a glance whether it still applies to your year.

Are the chapter weightage numbers in these articles official?

No. NTA does not publish chapter weightage for JEE Main or NEET. Any weightage you see on BrainStride is our own analysis of past papers, written as a range rather than a single number, and labelled that way on the page. Treat it as a planning guide, not as a promise about what your paper will contain.

Do I need a BrainStride account to read these articles?

No. Every article, chapter guide and free tool on BrainStride is open without an account. An account matters only when you want the 20-minute diagnostic, your weak-chapter map and a daily plan built from your own mistakes. The Starter plan that includes the diagnostic is free forever.

Reading about preparation is not preparation.

Take the 20-minute diagnostic, read your weak-chapter map, and decide afterwards whether you want the plan.
