UP Board Class 12 Mathematics Question Paper 2023

Mathematics set 324 AX has nine main questions, with subparts and internal choices.

Set 324 AX includes the degree of a differential equation, integration of cos²x and the angle between vectors. In the first question, raising both sides to the fifth power gives order 2 and degree 5. The order is the highest derivative; the degree is its power after the equation is written as a polynomial in derivatives.

UP Board Class 12 Physics Question Paper 2023

Physics set 346 BS includes conductor properties, a transistor circuit and a thin prism. For the prism question, use δ = (n - 1)A, where δ is the deviation, n is the refractive index and A is the prism angle.

For 346 BS Question 1, use the ideal-conductor electrostatic limit: the dielectric constant is infinite, not zero. Zero electric field inside a conductor should not be confused with a zero dielectric constant. For Question 3, equal deviation and prism angles in the thin-prism relation give a refractive index of 2.

The Chemistry paper includes Solid State, which is not part of the 2026-27 Chemistry syllabus.
