Experience as a Teaching Assistant (TA)
Again, please double-check with the university authority before placing your trust in my words, as the department's rules and regulations may change, which I might not be aware of at all times.
Typically, TAs are expected to work around 12 hours per week.
Usually no, but it can vary depending on the course. For example, if you are assisting with a course you did not previously take, you may need extra time to prepare.
Before each term, the department asks TAs to complete a form indicating their skills and course preferences. It is important to answer honestly and select courses you are comfortable with. Not listing many skills will not negatively impact your funding.
