Reviews of professor Philip Doi

Rating: 3.0/5, difficulty: 4.0/5
Doi is a really nice guy and he has a huge passion for math. While he does know his stuff, but he is really bad at making it clear for us to understand easily. We spent a lot of time going over the proofs for formulas but never really the application to certain problems using the formulas given so we were just made to guess.

Don't get me wrong Doi is a nice guy, but I would avoid if possible. I had a hard time following his lectures and he himself didn't seem too confident in what he was teaching. He would constantly mess up example problems and refer back to his notes to see if he was doing them right. Not too much homework but they can be hard, tests were easier tho.

Nice guy, adjusts grading and extra credit based on how the class does. Goes over problems sometimes without explaining the principles so studying by yourself is probably the way to go.

Philip is a good guy and isn't necessarily a bad prof, he just wan't super engaging. He would sometimes go off on tangents and could drone on. I learned what I needed to and passed, but would find myself falling asleep often, which I never really do. I'll cut him some slack though as he's fresh out of grad school and is still learning how to teach.

I have never been a part of more confusing lectures in my life. Having to take this class over zoom made it ridiculously hard to follow let alone, the poor teaching style. Though the classes are stupid hard and the homework even worse, he was SUPER accessible through discord which was a LIFESAVER!!
