I agree with just about everything else that's been said so far. Here's an example.

One lecture we were discussing how to run transactions serially. The professor mentioned that you can use a topological sort on a precedence graph to obtain the correct order of transactions. He then proceeded to give an incorrect explanation of topological sort. When a student pointed this out, instead of humbly accepting his mistake, Rosario snapped at the student and in a flustered tone, told us to just do a topological sort.

A student watching this all unfold might be thinking that since CS 180 is not a pre-req for CS 143 and since our professor doesn't even know what a topological sort is, this topic will probably never show up again.

Well, on our final, topological sort reappeared even though it had never been discussed again. I guess we were just expected to learn it on our own from one refrenece to it in lecture.

Experiences like this are what make the class so frustrating.

hard pass to this guy - one of the worst classes ive ever taken at ucla. he does not care about you learning; he just wants you to feel bad over things you probably missed in each lecture. He runs through about 100 + slides each lecture so good luck getting down every detail. he's snarky on piazza, and just a terrible professor in general. would never take again.

He blazes through ~120 slides a lecture at 8AM when everyone's tired & unfocused. Studying is hard because the material is seriously so boring, and he doesn't give out a list of topics for the midterm or the final. Save urself a headache and avoid this guy.
