I cannot stress enough how terrible an individual this excuse for a professor is.

The top review here mentions Rosario wanting to be like Eggert. Well, he is not Eggert. He's not a particularly good lecturer and I feel his opinions on what is important to know in a course are fairly antithetical to Eggert's. But that is possibly the result of teaching a databases course. Anyways, the course itself is not hard if you put in effort and engage with the material (which, to be fair, I did not), and I thought the exams were reasonable for the most part. His final grades were also very generous (I scored median on both the midterm and the final).

Rosario is a great lecturer, with incredibly detailed slides that he posts on Bruinlearn. He works at Google, and has a lot of good anecdotes from his professional career.

Some of the homeworks were easy, and some are more difficult, but they are all very straightforward.

There is an insane amount of content in this class. From the first to the last lecture Rosario will be lecturing for the entire class period, and he talks fast. Exams are completely open book, but extremely difficult. The curve is less generous than Eggert, but it's still there. I scored in the lower quartile on both the midterm and the final but still managed to scrape by with a B.
