LS4 wasn't an option but yeah. This is an eval for LS4.

Please don't be put off by Professor Jacobsen's lecturing during the first couple lectures. His lecturing style seems really boring and bland at the beginning but he's actually a fantastic lecturer if you actually sit through class or listen to his podcasts. He's also extremely helpful with any questions people might have after lectures. His class wasn't too difficult and I'd definitely suggest taking Jacobsen/Cohn. Their exams are pretty challenging but nothing was really unreasonable. I'd definitely suggest taking them over Siu. Siu is a fantastic lecturer but his exams personally seemed harder than Jacobsen/Cohn's.

LS4
Cohn and jacobsen are good, likeable lecturers. They teach well and are understandable. but at the end of the day the ta's write the exams and most of the problems either have nothing to do with what the professors put up on their lectures or are twice as long and twice as hard compared to other professors. And since its the grade that counts and not how much you like the professor, I recommend you stay away. Even professors like Pang have higher averages. Stay far far away.

LS4

Jacobsen taught the first three weeks (up until the first midterm) of LS4 and I really liked him. He presented the more basic, introductory concepts for genetics and I think he did a great job of keeping it simple and to the point. He is easy to understand, talks at a nice pace, and has a welcoming personality. Would definitely recommend.
