A CBSE Class 12 physics paper carries 70 marks of theory examination and 30 marks of practical assessment. The theory paper mixes objective, short answer, long answer and case-study questions, and the balance between numerical problems and derivations is the decision that most affects how it performs.
We do not write the questions. TurtleDock holds no question bank: this gives you the paper’s structure and the marks arithmetic, and the items are set by the subject teacher against the syllabus actually taught.
Physics at Class 12 differs from mathematics in one respect that matters for paper setting: the same syllabus content can be examined as a derivation, as a numerical problem, or as a conceptual question, and those three test genuinely different things. A paper that is 70 per cent numerical measures something narrower than the syllabus.
As with all board subjects, the current year’s sample paper and marking scheme published by CBSE are the authority. What follows is structure that has been stable, and the setting decisions that sit on top of it.
This is the axis a blueprint does not capture and a good setter thinks about explicitly. Decide the split before writing anything.
| Mode | What it actually tests | Failure if over-weighted |
|---|---|---|
| Numerical problems | Formula selection, unit handling, arithmetic under time pressure | Rewards drill; a student who has memorised formulae without understanding scores well |
| Derivations | Whether the chain of reasoning is held rather than the result | Rewards memorisation of standard proofs; heavily coached students dominate |
| Conceptual and assertion-reason | Understanding independent of computation | Hard to mark consistently; ambiguous wording produces appeals |
Thirty of a hundred marks sit outside the written paper, assessed in your own laboratory. That is a large share, and it is the part most vulnerable to being recorded loosely.
SchoolDeck holds these as components against the enrolment rather than as one number, for exactly this reason.
Phrased the way they arrive, answered so each one stands on its own.
There is no prescribed figure, which is precisely why it should be a recorded decision rather than an accident. Look at the current sample paper for the board’s own balance and depart from it deliberately if you have a reason.
No. It produces the blueprint — sections, counts, marks, cognitive spread. A derivation question has to be checked against what the class was actually taught, and only the teacher who taught it can do that.
As separate components with the assessor’s name and date against each, rather than one figure per student. Moderation and any later query both need to reach the component, not the total.
