Working through problems from past midterms and finals can be helpful (and reassuring). Please remember, though, that the coverage and emphasis does vary from year to year.

Studying tip: when studying past finals, try answering the questions without looking at the provided answers at all until you have a complete answer that you want to verify. Looking at the answer for a hint is tempting, but won't help you learn as much as figuring out the answer from your notes and textbook.

Note that midterms and final exam also include the formulas sheet and z and t tables (which are not included in the files linked below).
