About this app
By Dr. Shiv Patel, AIR 267 (690/720) in NEET 2020 & 2-time KVPY Scholar : I built NEET Codex as the ideal tool I wish I had during my preparation.
NEET Codex is built to act as your NCERT substitute for revision, so you never need endless re-reads again.
Providing almost 100% coverage of the NCERT textbook - every page of the NCERT is transformed into topic-wise line-by-line active-recall MCQs, helping you memorise, apply, and master Biology for NEET-UG.
WHAT MAKES NEET CODEX DIFFERENT
• Complete NCERT coverage - every line, diagram, numerical data, example, and table from the latest NCERT Biology textbook (Botany and Zoology both), transformed into NCERT-based, line-by-line MCQs. Nothing skipped, including scientist biographies and unit introductions.
• 20,000+ unique NEET MCQs, covering every angle of every NCERT concept so nothing catches you by surprise on exam day.
• Real MCQ variety - from factual recall to Assertion-Reason, Statement-based, Matching, Sequence, Multi-correct, Flowchart, and Case-based NEET MCQs, modelled on the last 10 years of NEET papers.
• Active recall design - NCERT MCQs train you to apply knowledge and reason through unfamiliar angles of a familiar concept, not just remember the textbook.
• Detailed answer key - every MCQ carries a "Justification" for the correct answer, an "Option Analysis" explaining why each wrong option is wrong, and the "NCERT Source": the exact NCERT line and page number it was built from.
• Exam-style wording - tricky phrasings like "all of the following are correct, EXCEPT" and "not incorrect," matched to how NEET actually asks questions.
QUESTION BANK
Browse chapter-wise, line by line, across NCERT Class 11 and Class 12 Biology, organised the way the NCERT textbook itself is organised.
• Active Recall - NCERT MCQs generated sequentially from every testable fact, definition, and diagram in the chapter. Solve these right after your first read to train active retrieval instead of passive highlighting.
• An "Essentials" filter narrows each chapter down to only its highest-yield NEET MCQs - a built-in crash course for when you're short on time.
• NEET Mastery - This section is your rank booster. Higher-order thinking NEET MCQs across Assertion-Reason, Statement-based, Matching, Sequence, Multi-correct, Flowchart, and Scenario-based formats - the questions that separate top scorers from the rest.
• Previous Year Questions - real NEET PYQs, mapped to the exact NCERT chapter and topic they belong to.
• Diagram & Data MCQs - a dedicated question for every NCERT figure and graph.
• Bookmarks - save any MCQ you want to revisit, and replay your saved list as a focused review quiz.
TESTS
• Custom Test - build your own NEET mock test series from any combination of chapters, question types, and topics, with a real total-countdown timer.
• Codex Tests - a test series of expert-curated, NCERT-based mock tests.
• AI Test Generator - generate a fresh NEET mock test from any NCERT chapter across a wide range of MCQ types.
• Real NEET scoring (+4 / -1 / 0), matching the actual exam.
• Pause and resume any mock test - progress saves automatically, so a closed app or dead phone never costs you a test.
AI DOUBT SOLVER
• A 100% NCERT-based AI doubt solver. Ask any NEET Biology doubt and get an answer retrieved directly from the NCERT textbook - never invented.
• Every response is cited by NCERT chapter, topic, and page, so you can verify it yourself instead of taking an AI's word for it.
STATS
• Track your daily streak, MCQs completed, and accuracy broken down by Recall, Mastery, and PYQ - so you always know exactly where to focus next instead of guessing.
3 complete NCERT chapters are free to try in full, no card needed. Built for NEET UG Class 11, Class 12, and droppers - you already know the content, you just need sharp, structured revision.
Fully updated for NEET UG 2027 and 2028, based on the latest NCERT Biology syllabus.
