<p>In ratemyprofessors.com , i've seen advices that tell students to "look for X GSI" etc. Is that possible?</p>
<p>For some classes it is possible, for some it isn't. For classes like math or chemistry, I don't think the schedule (or TeleBears) lets you know what GSI is leading the discussion/lab beforehand. Perhaps you could switch once classes start and you know which GSIs are leading which sections.</p>
<p>In classes such as R&C, you will be able to know who is teaching what class because it is actually being taught by a GSI.</p>
