Good opportunity for students with no significant downsides - Mitarbeiter (anonym) bei Purdue University: Mitarbeiterbewertung

Flexible to work when you're able on a week to week basis.

Professors not supported with graders (by the department) unless class size is 30 - even if the class size is 28.

If you already took the class that you TA a course, you already took there's less work for you to do to prepare for the labs. And you are just instructing the labs for the Engineering Technology department.

Grading is a lot of work, especially when the professor tells you to be stricter with grading, so you have to look at every detail.
