🧾 Exam Pattern – Question Distribution

Per sample marking scheme for 2025–26 

• Section A – 20 Qs × 1 mark (MCQs / Assertion-Reason) = 20

• Section B – 5 Qs × 2 marks = 10

• Section C – 6 Qs × 3 marks = 18

• Section D – 4 Qs × 5 marks = 20

• Section E – 3 Case-based Qs × 4 marks = 12

• Total = 80 marks

Internal choices (≈33%) are provided in each section; full choices are not allowed.

---

✅ In summary:

• Cover all six units thoroughly, with a heavy focus on Calculus (35 marks) and solid preparation in Vectors, Algebra, and Probability.

• Practice MCQs, Assertion–Reason, short answers, long answers, and case-based questions.

• Internal assessment (20 marks) consists of school periodic tests and activity work.
