I wish I could rate him lower than a one. He started off offering no extra credit and no curves on exams which would be completely understandable for a different type of class. The final is the ASCS and all exams are based off this, so it is very difficult and almost impossible for regular chem2 students to pass. Very annoying makes terrible jokes

Often the quizzes are take home. Is accessible and approachable for questions, but good luck getting answers if you don't know where to start. If you're shy, this may not work for you because his office is always full of students. Tests are not straightforward. Chem 2 has a high repeat rate, so the chances you'll pass the 1st time around are low.

Chemistry isn't meant to be easy, but he gives you the tools to be successful. This is college, nothing is going to be handed to you. You get the grade you work for.

People love to bad mouth teachers who's class they are not doing well in. Mr. Mamiya is a great professor/person to get to know. People say theres no extra credit but when he lets you take the quizzes home to work on, then come class time he lets you plug in the answers into the clicker, that is basically extra credit. Plus multiple other benefits.

Mamiya isn't a bad professor, but when he starts to fall off track from the syllabus, he tends to rush the lessons just to test over it. If you pay attention in class and do clicker questions, hw, and take home quizes you'll do fine on the test as long as you review. He cares for his students and wants everyone to pass.

He taught this class as if it was a refresher to AP Chem. He expects you to know basically everything BEFORE it is taught. Tests are unfair, their averages always failing, and he has over a 45% DFW rate. Unless you are going to Major in Chemistry, I don't recommend him to anyone. This is an overall bad class.

Dr. Mamiya is not an easy professor, but this isn't an easy course. He is a nice guy who is reasonable. He teaches his part, but he leaves the rest up to you. If you want to do well, you NEED to go to his study sessions and the SI sessions. Without that, I would have failed. The tests are hard and there is a lot of homework, but this is college.

Dr. Mamiya is one of the most amazing professors I have had throughout college. His lectures are very helpful, and attending class is necessary to take his tests, which can be challenging. He is thorough and helpful in class and out. When I was struggling in his course he would make sure I was doing well, an amazing professor and an amazing man.
