TA assignments are made with the following constraints in mind:
- We need many more TA’s for the intro courses than for the upper-level ones.
- Only required upper-level courses get TA’s; the other (elective) courses get graders, instead.
- For intro courses, a typical TA assignment involves one weekly discussion (for 8-9 weeks) plus one weekly lab (for 6 weeks).
- Since there are more lab sections than discussion sections in the intro courses, a few TA’s will be assigned to two labs (and no discussion).
