He makes you guess on things that hardly anyone would know or care about. Assigns homework before the topics are covered, and quizzes you over material not covered. Going to the SI sessions helps you more than he does. Not a fan of him as a teacher at all. Nice, but don't expect to do well unless you teach it to yourself.

Dr. A is is good professor in general. Chem151 is a general chemistry course and covers a wide array of topics. If you have good study habits it's really an easy course. The only issue is his lack of mastery of the English language. It makes conveying complex material difficult. This can detract from the material. Other than that - great course!

Dr. A is a very talented and intelligent teacher. To do well in this class you must study and attend class regularly, but not because he is a "bad" teacher by any means. If you put forth the effort in this class it tends to build on top of itself and gets easier as the semester goes. He's very nice and his accent is the one draw back.

A nice teacher who means well and wants his students to succeed. However his accent is very thick and since he doesn't use the white board- you don't always know what he is talking about. He also doesn't post his lectures online. which is fine normally- but if he is behind schedule he skips through them and you never know what was on the slides.

I would say one of the worse teachers I have had at NAU. He doesn't communicate what he will test you on. His study guides consist of 10-15 sentences. When teaching a subject he uses PPs and goes through them very fast, too fast. He waves his hands around as if that would make you understand a topic. Oh did I mention he doesn't speak english well?

He gets a bad rap. Give him a chance. He's a good professor, and he's MUCH BETTER IN 151 THAN HE IS IN 130. He is very nice and means very well. GO TO THE SI SESSIONS IF YOU ARE CONFUSED. There is a language barrier but it isn't bad. Those giving him a bad review likely didn't study and failed 130 - which is pathetic. APPLY YOURSELF.

Dr. A is a professor that gives you all the tools you need to succeed. Your hw and quizzes are easy points so do not settle for less than a 98+ on assignments (you will see how easy it is just very time consuming). Lecture notes are printed for you so just take good notes and study those for the tests. He loves smash burger. Will ask for a letter.

Lectures arent bad but then he hands you the test and its so hard. Doesnt give any form of study guide and tells to to memorize usually 3 packets worth of notes. Do that and still get trick ?s. Go in and ask for help and get basically told to do better. Barely tells his SI anything. Your lucky to get out of a test w/ higher than a 60%.
