qBio I Final exams: 2015
Answers are not posted. Study, and discuss among yourselves!
Note that as the curriculum has evolved, material from some questions on older exams may not have been covered in more recent years. In particular, as of Fall 2015, qBio has been split into two separate courses; qBio I nominally tracks the content of the Midterm exams posted here, and qBio II tracks the content of the Final exams posted here.
