Biology for Class 12, precisely diagnosed.
A Class 12 Biology diagnostic estimates ability across 13 NCERT chapters — from Reproduction Organisms through Biodiversity Conservation — so board exam prep targets chapters that still leak marks, not a single blended Biology score.

NCERT Class 12 Biology chapters in the diagnostic
Zetiq maps Class 12 Biology across 13 NCERT chapters. The adaptive test estimates ability separately in each — not as one blended Biology score:
- Reproduction Organisms
- Sexual Reproduction Plants
- Human Reproduction
- Reproductive Health
- Principles Inheritance
- Molecular Basis Inheritance
- Evolution
- Human Health Disease
- Microbes Human Welfare
- Biotechnology Principles
- Organisms Populations
- Ecosystem
- Biodiversity Conservation
- Topic-level ability for each NCERT chapter — not one blended Biology percentage
- Board exam prep that prioritises weak chapters before the exam
- Misconception-aware remediation after each adaptive session
- Works on any phone — no lab setup
Class 12 Biology chapters that build on each other
Some NCERT chapters assume earlier ones. Zetiq's syllabus order reflects these dependencies — the diagnostic respects them when estimating where gaps started:
- Learn Ecosystem before Biodiversity Conservation
- Learn Molecular Basis Inheritance before Biotechnology Principles
- Learn Organisms Populations before Ecosystem
What you get
Built for clarity, not noise.
IRT adaptive engine

What a Class 12 Biology gap map shows
School tests often report one Biology mark. A gap map separates chapters across all 13 NCERT units. Zetiq estimates topic ability from adaptive responses, then ranks which Class 12 Biology chapters to fix first.
- Which of the 13 NCERT chapters are secure vs still developing
- Whether the same misconception shows up across more than one chapter — and which chapters to fix first
- A study plan ordered for board exam impact — not alphabetical chapter order
How Zetiq helps Class 12 Biology students before boards
Students often re-read entire NCERT units before boards. An adaptive diagnostic estimates what they already know in each Biology chapter, surfaces the misconceptions behind wrong answers, and feeds an AI plan parents can follow.
FAQ
Questions, answered.
All three. Zetiq runs adaptive diagnostics and AI study plans for JEE Main, NEET, and CBSE Classes 8–12, with NCERT-aligned curriculum coverage.
Mock tests measure performance on a fixed paper. Zetiq's adaptive diagnostic estimates ability topic-by-topic, then turns mistakes into a prioritised study plan. Mocks still matter — diagnosis tells you what to fix before the next mock.
No. We do not guarantee marks. We give precise diagnostics and actionable plans. Improvement depends on practice quality and consistency — we make that practice targeted.
