The Problem
Every NEET aspirant knows the trap: read NCERT, re-read NCERT, forget everything, repeat. NEET Codex breaks the cycle with active recall.
Passive Re-reading Loop
You've read NCERT 10 times but still can't recall a specific fact under exam pressure. Re-reading feels productive — it isn't.
Fact Blindness
Scientific names, classifications, and exact data blur together. NEET punishes every missed detail, and passive reading can't fix it.
New Pattern Shock
Assertion-Reason, Statement-Based, and Case-Based questions catch students who only practised traditional MCQs from old resources.
Hidden Question Sources
MCQs from NCERT figures, tables, summaries, and scientist bios are entirely missed by students using conventional question banks.
Core Features
Every feature is built around one outcome: rank improvement through active recall and structured NCERT mastery.
01
Active Recall MCQ Bank
7,000+ questions covering every line, figure, and data table from Class 11 NCERT biology. Train your brain to retrieve information — not just recognise it.
02
NEET Mastery — HOTS Section
Assertion-Reason, Statement-Based, Case-Based, and Match the Column questions that mirror the new NTA pattern — the questions that separate toppers from the pack.
03
Previous Year Questions (PYQ)
Every PYQ mapped to the exact NCERT line it came from. See which parts of the textbook the NTA has tested before — and how many times.
04
Detailed Justifications
Every answer comes with a full explanation, option-by-option analysis for incorrect choices, and the exact NCERT source line citation.
05
Chapter-wise Analytics
Track your accuracy, speed, and mastery score for every chapter and section. A live dashboard that shows exactly where you're strong and where you're bleeding marks.
06
Mistake Review Log
Every wrong answer is automatically saved to your personal error log. Revisit, reattempt, and track whether you've genuinely mastered each weak spot.
07
Diagram-Based MCQs
Questions built around NCERT figures — the type of question most students completely miss during preparation but which appear regularly in NEET.
08
Streak & Progress Tracking
Daily streaks, completion milestones, and chapter progress rings keep you consistent. Consistency is the single biggest predictor of rank.
09
Section-level Organisation
Practice by chapter, part, section, or individual topic. Surgical revision when you're short on time, full sweeps when you want comprehensive coverage.
10
Continue / Resume
Every session is auto-saved. Pick up exactly where you left off — mid-chapter, mid-section — on any device, any time.
11
Timer Mode
Practise under timed conditions that simulate real NEET exam pressure. Build speed alongside accuracy so neither catches you off guard.
12
Quick Revision Tables
Curated last-minute power-up summaries for all high-yield data, classifications, and examples. Built to use the night before the exam.
Powered by AI
The NEET Codex app doesn't just give you questions — it learns how you think, identifies where you're fragile, and uses AI to close the gaps before exam day.
AI Question Generation
When you exhaust the base bank or need more practice on a specific concept, the AI generates fresh, high-quality MCQs from the same NCERT content — trained on the same question standards as the human-curated bank.
AI Mock Test Generation
Generate a full-length or chapter-specific mock test in seconds. The AI selects questions based on your weak areas, targets high-frequency topics, and balances question types to mirror real NEET paper patterns.
Personalised Weak Spot Detection
The AI analyses your error patterns across attempts, timestamps, and topics — then tells you exactly which concepts you think you know but don't. Targeted revision, not random practice.
AI Doubt Solver
Ask any question about a topic, concept, or explanation — and get an instant, NCERT-grounded answer. No more waiting for a tutor or scrolling through forums for a 10-second explanation.
Rank Prediction & Score Forecasting
Based on your accuracy, speed, and topic coverage, the AI estimates your probable NEET score range and rank band — giving you an honest picture of where you stand weeks before the exam.
Smart Revision Scheduler
Input your exam date and available hours. The AI builds a personalised daily revision plan that prioritises chapters by your mastery level and the historical frequency of those topics in NEET.
Content Architecture
The app mirrors how NEET actually tests biology — not how textbooks present it. Every chapter is organised into three distinct practice modes.
Part 01
Active Recall
Line-by-line MCQs derived from every sentence, figure, table, and inset box in the NCERT chapter. The foundation of your revision.
Part 02
Mastery (HOTS)
High-order thinking questions that match the new NTA exam pattern. This is the section that decides rank above 650.
Part 03
PYQs
Previous Year Questions mapped exactly to the NCERT lines they originated from — so you can see which parts of the textbook NTA keeps returning to.

NEET Codex is the tool Dr. Shiv Patel wishes he had as a student. Having mastered the exam himself, he designed a system that addresses the exact failure modes of NEET preparation — passive reading, incomplete NCERT coverage, and lack of structured practice on the new NTA pattern questions. What started as a physical book has evolved into an AI-powered app built to give every student a personalised path to their target rank.
