<p>Sorry for the delay. I will address the 3rd point.</p>
<p>I am a science major. The hard sciences will ALWAYS be taught by professors. Your TA’s will be grad students but the professors teaching the material will be experienced professors. I have had no experience with “vengeful professors” who want to inflict pain and misery for no other reason but to. They have always been passionate, excited, and engaged. I’ve always had the sense that they love to be there and many have even invited me to separate office hours to give me a thoughtful response to a question I had asked in email.</p>
<p>One professor gave very hard exams but it is a part of his teaching style. “I’ve taught you A and B through lecture and homework. Do you really understand the principles of A and B to make an intellectual leap to see and solve C for the first time in an exam?” He won the Quantrell Award for Undergrad teaching btw.</p>
<p>I’d say that 85% of classes will be taught by professors. The grad students I’ve had were spectacular as well. I wouldn’t have any qualms about the quality of teaching at UChicago. The professors are there because they want to be. Whether it is in the humanities, sciences, or any other department, there are great teachers.</p>
