NCERT Class 12 Biology tests — FAQs
How many chapter tests are there for NCERT Class 12 Biology?
13 chapter wise tests, holding 425 questions between them, plus a full book test for each Class 12 Biology textbook. Every chapter has its own test.
Are the questions taken from the NCERT Class 12 Biology textbook?
Yes. Each test is written from the text of that specific chapter — its definitions, processes, worked examples and the points the book emphasises. Nothing is pulled from a general biology question bank, so a question you get wrong always points back to a paragraph you can re-read.
Is there negative marking?
No. These are learning tests, not a ranking exercise. You get your score and the full explanation for every question the moment you submit.
Which is better to attempt first, chapter tests or the full book test?
Chapter tests first, one after each chapter you finish reading, while you can still tell remembering from recognising. Save the full book test for revision, when the whole book is behind you.
