centAIle is a NEET (UG) mock test platform built around one idea: a score alone doesn't improve your rank — knowing why you lost marks does. Every mock follows the real NEET pattern: 200 questions across Physics, Chemistry, Botany and Zoology, 200 minutes, +4 for a correct answer and −1 for a wrong one, out of 720 marks. Questions are original, written in the style of previous-year NEET papers and grounded strictly in the NCERT Class 11 and 12 syllabus, with chapter-wise weightage matched to the official NEET blueprint.
After every test — including the free sample — centAIle projects your marks onto the 720 scale and predicts your All India Rank and percentile using official NTA NEET marks-vs-rank data. More importantly, it shows how many marks are recoverable from careless slips, time pressure and weak concepts, and how much rank each fix is worth.
Premium students train weak chapters with adaptive practice that covers every sub-concept — from Mendelian genetics and pedigree analysis to thermodynamics and electrodynamics — with a mastery map, a mistake bank with spaced review, and difficulty that rises as you improve. Start with the free NEET sample test — no sign-up needed to attempt it.
