🎁 Study materials & daily practice — free forever
Passes & Licenses
Every textbook answer, previous paper, practice question and daily test on Brain Grain is free, no login required. These optional passes don't lock any of that — they add the layer practice alone can't give you: personalised analysis, full-length exam papers and institution tools. One-time payments, no subscriptions.
Time-boxed passes valid through your exam — not monthly plans. The questions stay free; you're paying for the analysis and the real papers.

✓ The free promise doesn't change
Nothing that is free today becomes paid tomorrow. Samacheer and NCERT answers, previous papers, MCQ practice, the daily tests and the teacher toolkit are free for everyone, forever. The rule we hold ourselves to: we never charge you for finding an answer — only for helping you improve faster, or manage a batch.
Questions
Are these subscriptions?
No. Every one is a one-time payment valid for a fixed period (through your exam, or a set number of days). Nothing auto-renews and there's no card on file.
What stays free?
All study materials and daily practice: Samacheer & NCERT textbook answers, previous-year papers, MCQ practice, the daily TNPSC test, all 106 NEET & JEE chapter tests, TNTET Paper I & II practice, and the teacher toolkit. The passes only add analysis, full-length papers and institution tools on top.
Do you have a Teacher or Family plan yet?
Not yet — we only list what's actually built and on sale. The free
teacher toolkit (worksheets, lesson plans, question papers) is live today; a paid Teacher workspace is planned, and we'll add it here when it exists, not before.
How do I pay?
Via Razorpay — UPI, cards or netbanking. Open the pass you want above and the checkout is on its page. Aspirant passes need a 30-second sign-in (Google or OTP); the institution license just needs your institution name and a group code.
Refunds?
Yes — each pass has its own promise on its page (for example, the TNPSC pass refunds if your predicted band hasn't moved in 30 days, or if something's broken we can't fix in 48h). Email
