60 questions covering every lecture deck in the Exam 1 block, the same number from each topic. No question appears in more than one form, so working through all five gives you 300 distinct questions. The live sessions (small groups, journal days and project time) have no deck and are not included. Every question cites the slide it is built on.
Answers reveal only after you choose. Your score and a breakdown by objective appear at the end, with a review of everything you missed.
