CUET Biology mock tests and practice

CUET Biology is an NCERT-line paper. The syllabus is built from the terms, diagrams and examples in the Class 12 book. Close readers have the edge, because an option that changes one word of the book is an easy trap for anyone who revised from notes.

Where Biology marks are won

Genetics and evolution carry the reasoning questions: crosses, ratios, inheritance patterns and the molecular basis of inheritance. Practise them until the ratios are instant.

Reproduction, human welfare, biotechnology and ecology are recall-heavy. Statement and match-the-column questions test whether you know the exact example, organism or process. Short timed sets show quickly which chapters you only half know.

How MockMob turns Biology practice into marks

  • A fresh paper every time

    There is no fixed list of Biology mocks to run out of. Each paper is built the moment you start it, from the 450 Biology questions in the bank, with questions you have not answered put first. Pro puts no cap on how many you take; on Free each paper uses credits.

  • See exactly where the marks went

    After every mock, the review shows the time you spent on each question, every answer you changed and the Biology chapter behind each miss. Chapter review is free after every mock.

  • Fix the mistake, then prove it

    Mobi fixes a mistake for good: why your pick looked right, where it breaks and what to remember, written from the official key. Fresh questions on the same idea come back later to check the fix held. One credit a fix.

  • Ask Mobi about any Biology doubt

    Stuck on a concept? Ask Mobi. Your doubt is answered and tested on two new CUET-style questions, for one credit. Everything Mobi reads from your own record is free.

  • Sit a paper with your Mob

    A Mob is up to five friends on the same ten questions each week, free of credits. When you have all sat it, compare how each of you picked.

CUET Biology questions, answered

Is NCERT enough for CUET Biology?
NTA sets domain subjects as per the NCERT syllabus, so the Class 12 book is the core. Pair close reading with timed objective practice, because near-miss options are easy to fall for.
Which Biology chapters are the most reliable marks?
Ecology and biotechnology are compact and quick to revise, and genetics rewards practice. Chapter review after each mock shows where your own marks went.
How is the CUET Biology paper marked?
50 questions in 60 minutes, all compulsory. A right answer is +5, a wrong one is -1, and a question left blank is 0, so the paper is out of 250. MockMob marks every full mock the same way.
How many Biology mocks can I take on MockMob?
As many as you want. The Biology bank holds 450 checked questions (counted 25 Oct), and each paper is built from it when you start, with questions you have not answered first. Pro has no cap. On Free, each paper uses credits. A long run of papers can bring back a question you have seen; NTA mode names any repeat on the paper.
