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. These forms cover the six LECTURES. The exam also covers Lab 1, for which no material has been handed out; when it is, it gets folded in and these are rebuilt. You are not expected to recall reference ranges — where a value matters, its scale is given in the question. Every question cites its slide.
Answers reveal only after you choose. Your score and a breakdown by objective appear at the end, with a review of everything you missed.
