Past Exams By Year
HKN and TBP have archived more past exams.
1
61C changed from 2 midterms to 1 midterm starting in Spring 2021. The midterm is somewhere in-between the 2-midterm equivalent in terms of scope, but closer to midterm 2.
2
Quests are shorter than midterms and held earlier in the semester, before the drop deadline.
3
Before Fall 2017, CS 61C was taught using the MIPS ISA. The assembly and datapath exam problems from this period are less beneficial to review.
