Ten NEET questions a day. The same ten for every student in India. Prep Arena finds what you are weak at and keeps bringing it back until you are not. No lectures, no playlists — ten questions every morning, marked the way NEET marks them, ranked against everyone else who played the same ten. TODAY'S NEET 10 — The same set for every student, every day. Sixty seconds a question. Plus four for right, minus one for wrong, nothing for skipped, so your score today means what it will mean on exam day. Finish and see your rank in India, in your state and in your district, and exactly how many marks the guessing cost you. WHAT YOU GET WRONG COMES BACK — a day later, then three days, then a week, then three weeks. Right three times running and it is yours. PRACTICE ANY CHAPTER — all 79 chapters, 4,922 questions written from NCERT and 939 real questions from NEET 2016–2023, each carrying its year.
