In my opinion, Professor Dolecek is severely underrated on bruinwalk, and I definitely enjoyed her class the most this quarter.
Dolecek's lectures reminded me of those MIT open-class videos that I have seen on Youtube. She was very organized and explained the concepts pretty well. She always answered questions that people had and encouraged class participation. This is why even though her lectures were recorded, most people still preferred to show up in person. I think the biggest downside about her lectures was that she handwrote all her notes on the whiteboard and it could be hard to read sometimes. Regardless, you could always ask her to clarity what each symbol meant.
The exams were okay. I went over her past exams in the test bank, and I realized that her exams used to be a lot harder. Maybe that is why she has such bad reviews on bruinwalk. Anyway, our midterm and final were pretty well designed and similar to the HW, with maybe one or two questions that were kind of challenging/tricky. If you understand the HW, you should get at least a 90 on the exams. Be sure to check your answers though, we did not get to use a calculator during the exams and they did not grade our exams very nicely (you would lose a lot of points for making an algebraic error).
Some of the HW questions involved coding in matlab and there was a matlab project. I did not find coding in matlab particularly difficult with the help of the internet.
