Make this session count.

Two collections: 3 foundation papers and 3 distinct original mock papers, each with matching sectionals. Mock papers have 12 original passages of about 300–350 words each across the forms, 15 distinct reasoning sets and 66 QA questions. Each full paper uses a historical 68-question structure (24/22/22), not a confirmed 2026 count. Foundation forms reuse templates. All difficulty labels are provisional; no percentile or mastery claim is made. Standard timing is 120 minutes; extended practice is 160 minutes.
