Compare your performance across 3–4 exclusive papers. Create a heat map of weak areas—for example, if you consistently lose marks on financial strategy questions in exclusives, prioritize that domain.
Expect questions focusing on the properties of integers, prime factorization, and modular arithmetic. Past papers frequently feature problems requiring students to find the last digit of a massive exponent or determine the number of trailing zeros in a factorial product. 2.

In SIMSO, a blank answer gets 0, but a partially correct proof might get 4 out of 7. Exclusive resources show you the official rubric . You learn specific phrases and lemmas that trigger points. For instance, in Number Theory proofs, writing "By the Well-Ordering Principle" is often a mandatory 1-point step that students miss.
