<p>What are the responsibilities of a TA? From my college days, the TA only was there to reinforce what was taught at the lecture. They handled the labs (graded them) but we followed the lab manual instructions so unless we were totally lost, we didn’t bother to ask them for help. Is the TA teaching new material that the professor never covers? </p>
<p>The “understandability” factor exists with the professors too! DS had a few but he worked his way through it (study group etc.).</p>
