Worked solution P22-Tough-1. The official averages are 2.14 minutes per MCQ and 22.5 minutes per FRQ; a personal 3-minute reserve must be subtracted from the relevant 90-minute section before allocating time. $$\text{MCQ mean time}=\frac{90}{42}=2.14,\text{FRQ mean time}=\frac{90}{4}=22.5.$$ With a 3-minute reserve, allocate (90-3=87) minutes to first-pass work.

Students may use an approved handheld graphing calculator and the built-in Desmos graphing calculator in Bluebook. A derived rate such as (90/42=2.14) is reproducible arithmetic. A calendar date, device rule, or score boundary is administrative evidence and cannot be derived. Interpretation: Accuracy for id and supplies depends on separating quoted policy, transparent arithmetic, historical comparison, and editorial inference. Validity: Compare page year, page owner, update date, standard versus late testing, and whether the statement is a rule or an illustrative practice recommendation. Error to reject: Do not average conflicting facts, select the newest-looking search result, or present a plausible inference as an announced policy.
