Reviews of professor Zachariah Riel

Rating: 5.0/5, difficulty: 2.0/5
Dr. Riel is a very.. unique person but his lectures are always clear, concise, and it is evident that he knows what he is talking about. The exams are fairly easy but beware of the final exam. If you know what you're doing and study somewhat, you will be able to get an A.

Acted like he taught things that he never taught then would get mad at the class for not knowing what he was talking about.

He is overall a really good guy, and taught well, but the homework he gives is a complete waste of time, but is worth 70% of your grade. My best suggestion is to focus way more on the suggested problems and the reviews than the actual homework (but you should get it completed). He is great help outside of class. Beware of the final!

His lectures are SO confusing. He constantly asks if we understand and I can assure you half the class does not. He overcomplicates calc, which is fairly complicated enough when your in an engineering school. If your not solid in the topic of calc, don't take him for math 140.

Try to avoid this professor for math 140 if you solve a problem but not his way you get no points, he also doesn't allow calculators and no equation sheet, he also assumes that everyone has taken this class in high school not beginner friendly.

Prof. Riel is okay if you have a background in calculus. If not go to the tutors for any questions, going to his office hours makes you more confused. He is also pretty condescending

This class was pretty easy in my opinion because the practice exams and notes really help you prepare for the exams. As long as you sty
