What is Brain Grain?
Brain Grain is a free practice app for Tamil Nadu learners. Pick what you are preparing for and it opens on your own screen: your streak, your weakest topic, and the next question in your syllabus. There is no login wall, no fee, and no advertisement between you and an answer.
Government exams. TNPSC Group 1, Group 2, Group 2A, Group 4 and Mains, with previous-year questions, unit-wise study material and a daily test every morning. SSC CGL, IBPS PO, RRB NTPC and UPSC CSE practice sets are here too, in the same format.
School, Class 6 to 12. Samacheer Kalvi chapter answers and MCQs for every subject, NCERT solutions for CBSE, public exam question papers, and a timed revision challenge for SSLC and HSC students.
NEET and JEE. Chapter tests across all 106 NCERT chapters, marked instantly and ranked against everyone else who took them, so you know where you stand rather than only what you scored.
Teacher exams. CTET Paper I and Paper II and TNTET practice, including child development and pedagogy, bilingual throughout.
Every question is available in English and Tamil, and everything above is free.
