Sixty questions drawn from every lecture in the Exam 1 block, in exam proportions rather than at random — each of the six lectures contributes ten questions to every form, so this is a genuine cumulative rehearsal and not a sample of whichever topic had the most questions written for it. Questions are reused verbatim from the topic quizzes, so nothing here can drift from the material it is summarizing. No question appears in more than one form, so working through all five gives you 300 distinct questions. The two immunity lectures are the heaviest in the block — Lecture 5 alone runs 93 slides against eleven objectives — but they get the same ten slots as everything else, which is the point of building the forms this way. Every question cites its slide.
