Weights and Statistics

Weights

Your scores will be weighted roughly as follows:

prelims   40%
final exam  40%
homeworks   20%

Your two lowest homework scores will be disregarded, and the remaining homeworks will be weighted uniformly.

(With the exception of the modes, these data can also be found in the grading notes-- for past homeworks and exams, please see the archives.)

Caveat: the numbers listed in the "out of" row do not necessarily reflect the relative weights of the homeworks.

(Also, the homework statistics, though useful, should be taken with a grain of salt, since they are currently aggregated over the set of students who turned in that particular homework instead of being aggregated over the set of all CS280 students.)
