CBSE Class 12 Science QB Bundle (Physics, Chemistry, Biology and English)

If you are taking PCB with English Core, you are sitting four papers and 290 marks of theory. This bundle covers all four.

Physics, Chemistry and Biology are each 70 marks of theory with a 30 mark practical. English Core is 80 marks of theory with 20 marks of internal assessment. The weighting is uneven and worth knowing before you plan your revision. In Physics the board marks groups of units rather than single chapters, so electromagnetic waves and optics carry 18 marks between them while electronic devices carries 7. In Chemistry the heaviest single chapter is Electrochemistry at 9 marks, followed by Aldehydes, Ketones and Carboxylic Acids at 8, while Haloalkanes, Alcohols and Amines carry 6 each. Each book prints its own weighting table so you can see where the marks sit.

What’s inside:

• Physics, 842 questions - 55 in every one of the 14 chapters, plus 72 diagram and graph questions in two dedicated sections.

• Chemistry, 660 questions - 55 per chapter across 12 chapters, including 60 HOTS questions and 36 case studies.

• Biology, 896 questions - 56 in every one of the 16 chapters, numbered straight through, with a worked answer for each.

• English Core, 315 questions - 210 one mark, 63 short answer and 42 long answer across 21 chapters.

• The same section skeleton in all three sciences - multiple choice, assertion reason, very short, short, long answer with an OR choice, case based and HOTS, so you are not relearning the layout for each subject.

• Diagrams you have to draw, not only read - Physics Section F gives you the charge or circuit configuration and leaves space to draw. Section G gives you a printed graph and asks you to read values off it and explain the physics.

• The real board paper structure printed alongside the practice - the Chemistry book sets out the actual paper, 16 objective, 5 very short, 7 short, 2 case based and 3 long answers for 70 marks, and tells you where its own section letters differ from the board’s.

• Numericals set out as Given, Formula, Substitution, Answer - the format that earns method marks even when the final figure goes wrong.

• Removed syllabus material kept and labelled - every chapter and question outside the current course carries a notice, so you can skip it before the boards or keep it for NEET.

Physics covers all 14 chapters, starting at electric charges and fields and finishing on semiconductor electronics. Chemistry covers 12 chapters, of which ten carry board marks. Polymers and Chemistry in Everyday Life were removed in the 2023-24 rationalisation and are kept as practice only. Biology covers all 16 chapters, of which 13 carry board marks. Reproduction in Organisms, Strategies for Enhancement in Food Production and Environmental Issues were also rationalised out and are marked accordingly. English Core covers eight Flamingo prose chapters, five Flamingo poems and eight Vistas chapters, of which Should Wizard Hit Mommy and Evans Tries an O-Level sit outside the prescribed syllabus. Counting only what the board can ask you, that is roughly 2,405 of the 2,713 questions. The rest is labelled, so you decide whether to spend time on it.

How to use it: Read the NCERT chapter first and understand every derivation before you open the question bank. Then work one section at a time with the answer key closed. In Physics, write GIVEN, TO FIND, SOLUTION and CONCLUSION for every numerical and put SI units at every step, not only on the final line. In Chemistry, attempt the hint only after a real first try, because the hint tells you which idea is being tested rather than the answer. In Biology, do the assertion reason set properly, since those five questions per chapter are where most marks leak. Leave Sections F and G in Physics until the chapter is otherwise finished, then practise them on paper rather than in your head.

These are practice questions with worked answers, not textbooks. You will still need NCERT for the theory itself.
