Before the papers
How to Attempt Each Paper
The four sections and how each one is marked
Section A (A1–A10). Single correct. Exactly one option is fully right. Each of the other three fails on at least one precise point.
Section B (B1–B20). One or more correct. One, two or three options may be right — never zero, never all four. One wrong tick voids the whole question.
Section C (C1.1–C4.5). Passage based. Four consultation records, five questions each. Every record contains planted noise — details that belong to no placement. Multiple-correct questions here follow the Section B rule.
Section D (D1–D10). Assertion–Reason. Mark (A) if both are true and R explains A. Mark (B) if both are true but R does not explain A. Mark (C) if A is true and R is false. Mark (D) if A is false and R is true.
In each chapter, 36 questions are Very Hard and 24 are Hard — the level is printed nowhere on the questions, and everywhere inside them. All Answer Keys and full explanations — each naming the trap it was built on — are gathered in Part II, chapter by chapter, after the six papers.
