The Problem

Sound familiar?

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

Everything you need. Nothing you don't.

Every feature is built around one outcome: rank improvement through active recall and structured NCERT mastery.

Core

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.

Core

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.

Core

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.

Core

04

Detailed Justifications

Every answer comes with a full explanation, option-by-option analysis for incorrect choices, and the exact NCERT source line citation.

Core

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.

Core

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.

Core

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.

Core

08

Streak & Progress Tracking

Daily streaks, completion milestones, and chapter progress rings keep you consistent. Consistency is the single biggest predictor of rank.

Core

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.

Core

10

Continue / Resume

Every session is auto-saved. Pick up exactly where you left off — mid-chapter, mid-section — on any device, any time.

Core

11

Timer Mode

Practise under timed conditions that simulate real NEET exam pressure. Build speed alongside accuracy so neither catches you off guard.

Core

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 intelligent layer
that no other book has.

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 Feature

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 Feature

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.

🎯
AI Feature

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 Feature

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.

📈
AI Feature

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.

🗓️
AI Feature

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

Three-part system.
Total NCERT command.

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.

  • Standard conceptual MCQs
  • Diagram-based questions
  • Integrative multi-concept questions
  • Topic-level organisation within sections
  • NCERT source line citation for every question

Part 02

Mastery (HOTS)

High-order thinking questions that match the new NTA exam pattern. This is the section that decides rank above 650.

  • Assertion-Reason questions
  • Statement True/False sets
  • Case-based reasoning questions
  • Match the Column
  • Multi-statement analysis

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.

  • Year-tagged questions
  • Source-line mapping to NCERT
  • Topic-level filtering
  • High-frequency topic scoring
  • Trend analysis over past 10 years

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.

FAQ

Common questions.

Is this based on the latest NCERT syllabus?
+
Yes. NEET Codex is fully updated to align with the latest NCERT Biology Textbook and the current NEET-UG syllabus. Every question is sourced directly from the most recent edition.
How is this different from other MCQ apps and books?
+
Most MCQ resources give you a static bank of questions. NEET Codex is an active recall system with an AI layer on top. It is the only resource that covers every single line, figure, and table from NCERT — not just the highlighted parts. The AI then personalises practice based on how you're actually performing, not just how many questions you've done.
Is Class 12 available yet?
+
The Class 11 question bank — 7,000+ MCQs — is complete and being integrated into the app. Class 12 is in active development and will be added to the app once validated. Both classes will be accessible under a single subscription.
What exactly are the AI features and when will they be available?
+
The AI features — including question generation, mock test building, doubt solving, rank prediction, and smart revision scheduling — are planned for a later phase of the app. The core question bank and quiz engine are live first. AI features will be added progressively once the base app is fully validated.
Can I still order the physical book?
+
Yes. The original 2-volume physical book set for Class 11 is available to order now via Razorpay. The book and app are separate products — the book is ideal for initial passes and desk study, while the app adds analytics, AI, and interactive practice.
When will the app be on the App Store and Play Store?
+
The app is currently in active development. iOS and Android releases are targeted soon. Contact us on WhatsApp or Instagram to stay updated on the launch timeline.
Is there a free trial or sample available?
+
A free sample PDF is available to download from the original website to preview the question quality and format. The app will include a preview mode for at least one complete chapter before a subscription is required.
