Reviews of professor Michal Szostak

Rating: 1.0/5, difficulty: 4.0/5
Goes very fast and doesn't really try to explain things well. Barely uses the whiteboard and is almost breathless when he speaks. Expect reading and understanding on your own to pass. 
Horrible.

for the people who want to apply for his PhD., this guy doesn't have any ideas, and the lab environment is bad, no 
 schlenk line,no glove box, and many people use only one vacuum pump. I feel this is not a good choice to do a Ph.D. or postdoc in his lab. suggestion from a former.

Honestly, this class was very easy. Professor Szostak truly wanted you to do well in his class and it was obvious based on his exams. There's 2 midterms and 1 final, and you drop your lowest midterm grade. All exams are MC questions and you'll typically receive 8-10 bonus points (including final). He does fly through his lectures, so study at home!
