Reviews of professor M Khaled Arafeh

Rating: 1.0/5, difficulty: 3.0/5
The optional textbook he recommends in the syllabus teaches you better than his lectures.

Rating: 2.0/5, difficulty: 4.0/5
he doesnt care at all. goes through stuff really fast, barely explains, and during lab he is gone for more than 90% of the time. had to self teach almost all the material

there was alot to remember with any chem class but his teaching was pretty accurate was told what to know and such with simple examples the final was a bit harder but other wise was chill

OChem is a difficult course regardless of the professor. Khaled was good in the sense that his lectures were comprehensive and his exams related to the lectures. Office hours are full because he goes into depth answering questions. Nothing is confusing about having him as a prof and makes Organic Chemistry seem simpler than it is.

Doesn't respond to emails, teaches confusingly, and at times doesn't even know the answers to the questions he's demonstrating. He comes in late fairly often, but doesn't make up the time. 
The slides he puts online have sections missing, so you have to come to class or get the missing parts from a friend.
You'll need to teach yourself this course.
