Two ways centAIle makes you exam-ready

Not just scores — the deepest analysis in NEET prep, plus the training to act on it.

📊

Deep mock-test analysis

Every mock is X-rayed so you know exactly where your rank is leaking.

  • Error DNA — careless vs concept gap vs time-pressure vs guessing
  • Recoverable marks — how many you can win back, and from what
  • Section & topic accuracy, negative marking, time-per-question
  • Top-3 "do this next" priority fixes + explanation for every question
🧠

Topic-wise deep analysis & training

Drill down to the sub-concept and turn weak ones into strong ones.

  • Per-concept mastery — strong/weak within a chapter, not just "weak"
  • Adaptive practice — correct → harder, covering the full concept range
  • A mastery map across all 77 NCERT chapters that fills as you improve
  • Never repeats a question you've seen · instant feedback & explanations

Frequently asked questions

What makes centAIle different from other mock-test apps?
Most apps give you a score. centAIle goes beyond scores, into insights — a concept-level deep analysis of every mock and every topic — exactly which concepts you're weak in, why you lost marks (concept gap vs careless vs time vs guessing), how much is recoverable, and what to do next. Then it trains your exact weak concepts.
Do I have to sign in to try it?
No. Take a free 40-question sample test across all four NEET sections without any sign-up. You'll see your score instantly — sign up only when you want the full analysis and the complete mock tests.
How does the topic-wise deep analysis work?
Every NCERT chapter is broken into its sub-concepts (e.g. Genetics → Mendelian laws, linkage & recombination, pedigree analysis). As you practise, we track mastery per sub-concept, so you see precisely which parts of a chapter are strong and which need work — not just 'Genetics: weak'.
Are the questions like real NEET?
Yes. Questions are generated in the style of previous-year NEET papers — same flavour, traps and difficulty — strictly from the NCERT Class 11 & 12 syllabus, and original (never copied). They're graded easy / medium / hard, with +4 / −1 marking out of 720.
What do the paid plans include?
Free: 2 mock tests with section-wise scores. Standard (₹99): all mocks + deep analysis (Error DNA, recoverable marks, time, weak/strong topics) + explanations. Premium (₹199): everything in Standard + topic-wise adaptive training, the mastery map, difficulty-wise papers, and personalised weak-topic practice.
Can I see what I'll get before paying?
Yes — the free sample test, the analysis preview, and the dashboard preview on this page all show exactly what you'll receive. You only pay when you choose a plan, and payment happens right after you pick one.

NEET mock test series online — free practice with AI analysis

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.

NEET rank predictor — know where you stand today

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.

Topic-wise NEET preparation across all 77 NCERT chapters

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.
