Exams Sorted By Semester
“ref” = Reference card provided during the exam.
“clarifs” = Clarifications issued during the exam.
If an exam doesn’t have the reference card or clarifications linked, it means we don’t have access to it, so please don’t ask.
Note for students solving past exams:
Prior to 2025, we created custom reference cards for each exam. Different semesters would sometimes use different names for similar methods. For example, the method for returning, but not removing, the smallest item could be called
peekorgetSmallest. Which name you’d write on that semester’s exam depends on what that semester’s reference card said.As of 2025, we’ve standardized on using the same reference card for every exam, so the method names used on exams should now be more consistent.
Regarding what method names you can use on the exam, keep in mind these two lines from the front page of all recent exams:
- “Unless otherwise specified, you may assume that everything on the reference card has been imported.”
- “If an implementation detail is relevant, it will be explicitly noted in the question.”
