Build a current 42-question multiple-choice set from an 80-question bank covering all five revised units. Every item has four answer choices, matching the 2027 exam change. The bank excludes retired core topics and includes probability and regression shared-prompt practice.
Choose all 80 questions, one unit, or a random 42-question exam set
Every one of the 55 current CED topic codes is mapped to practice
This is a coverage map, not a claim that one question creates mastery. Topics with only one mapped item should be revisited through the book, FRQ sets, or additional unit practice.

The revised exam reduces answer choices from five to four but adds two shared-prompt sets. That makes reading the common prompt carefully and maintaining consistent definitions across linked questions especially important.
Parameter? Distribution? Design? Inference method? Regression interpretation? This prevents formula-first guessing.
Concept, method selection, condition, calculation, interpretation, or careless reading.
Do not restart from scratch; keep n, p, variables, or regression model definitions consistent across all three linked questions.
