Reviews of professor Seiji Takemae

Rating: 3.0/5, difficulty: 4.0/5
Pros:
Very nice professor. Smart guy. Diligent. Starts and ends class exactly on time. No proctorio. Gives a lot of partial credit on tests. 
Cons:
Tests are HARD. Really needed help at times in a class discord group. Chegg is 100% needed, even if you are great at science. He could work on his confidence as a professor.

Rating: 4.0/5, difficulty: 1.0/5
Pros: Easy tests, explains concepts thoroughly, very lenient.
Cons: Long lectures, hard to get a hold of.

Very easy to get a B and C.
Takes a little more effort to get an A, but completely possible.

Provides a PDF of the text, but homework is online with an $80 price tag. Lab work is also online for $20. Gives partial credit on exams if the answer is wrong as long as the work is shown, and tells you where the error was. Did not finish writing final exam in time, and sent an email the day it was scheduled. Mumbles during lectures.

If you are weak in physics or math, by all means, take his class. His tests are not proctored and if you take the exam at night, all of the answers will be available on Chegg for you. 
YOU DO NOT NEED TO STUDY OR ATTEND LECTURE TO GET AN A IN HIS CLASS. IT DOES NOT GET ANY EASIER THAN THIS!! (on a side note though, this professor is irresponsible)

When Someone teach any class, he/ she must have level of voice so that all students able to hear. His voice is too soft and low, sometimes he can not control the class. Overall nice person. If You want A or B , Dont think to miss any of his class and must understand material. Easy C .

Extremely sweet and shy professor but I went in with the expectation that this class would be easy and could have put more into it. With that said lecture is from the minute class starts until the minute it ends (with 20 min break of course) Don't even think about leaving early, grading is a bit harsh.

Professor gives very hard tests and there is no extra credit. Very long lectures and boring. If you can, choose another professor instead.

Some may find Professor Takemae's class a bit tedious, but I found it good and helpful. He is shy, timid, and soft-spoken so some rude students take advantage of that, but he is super sweet and truly cares for his students. He replies fast to emails, is attentive during 1:1, and answers any question in depth. I see no reason not to take him again.
