He's a nice guy and good speaker but his lectures and notes do not explain how to solve a lot of the problems you will be asked for on the exam.

Entirely incomprehensible. He goes on for the entire lecture about the environment and other useless stuff you will never need to know, but he skips over important concepts like Hess's Law and the Arrhenius equation.

Phys chem should be mostly quantitative, but the prof made it completely qualitative. The stuff in this course is super blurred, and part of the stuff is not academic related. The midterms were harder than the previous ones because the course is still evolving. Memorize everything in his slides, then you can get an A.

I dreaded physical chemistry before meeting Prof. Barrett. He made the subject much more interesting by incorporating current topics!

A professor that genuinely cares about his students. Once he forgot to record a lecture using the cool system, so he took the time to re-recite his lecture in his office and post it for students that missed the class. His exams are fairly straight forward. Be sure to do the practise problems and read the slides a couple of times and you'll be fine

Who cares if a prof is nice or not, what is important in univesity is the level of clarity in which the class is given.

He's a smart guy and his research is cool but he's not the greatest lecturer and he tests on random facts he mentions once in class that are nowhere to be found in the textbook.
