6BL wasn't too bad, but it's definitely dependent on how lenient your TA is. The last lab was definitely a little difficult, but if you ask your TA for help, they'll probably help if you're struggling.

Prof. Popescu and knows the material well, but she's only ever taught lower-division courses meant for non-majors and it shows. Avoid for upper-division physics courses.

GOAT. I had her for all of 7 series and she is such a passionate lecturer and engaging with her students in and outside of lectures. She is really good at emphasizing the intuition side of physics which can be frustrating but is rewarding. HWs can be long and attendance gives you a small boost in grade but not enough to consider "mandatory".

Phys 6CL was not bad, and the experiments were pretty interesting. Some of the prelabs are kind of long, so get ready for that. My TA was a really lenient grader, which was nice.

I don't have anything against this professor. Her lectures were fine, but boring. The section for the class was not designed too well. Sometimes I would get lost during lectures. The expectations on how to do well are made obvious by the weekly homework assignments and practice test problems. Shouldn't be too hard if you just put in the effort.

Paula is not awful for the intro classes like 7A and 7B, but when the material gets much more conceptual and hard (such as 7C) her lectures just become rambly and impossible to understand. I emailed her at least 4 times within the last two weeks of class, and she didn't respond to a single one. Take Daddy Koutralakis instead he's much sexier.
