Reviews of professor Zachariah Riel

Rating: 2.0/5, difficulty: 4.0/5
Nice guy only reason I got a good grade was because it was precalc and I had taken it before in high school. If you are a calc 140 or calc 141 student I would steer clear. His explanations are confusing and made me not understand topics that I had very good grasps in. Also have to pay $120 just to do homework just avoid if you can.

Clear lectures w/ guided notes, fairly helpful in class, textbook only used for studying, not needed for assignments, homework doesn't help for tests as much as optional practice problems, but homework is a big part of the grade

I had no problems with Professor Reil. Pretty nice guy and will explain anything you need. The homework was pretty tough and had questions we didn't learn in class. The exams are exactly like the study review exams.

No equation sheets or calculators on exams, be ready to spend hours upon hours of homework in the worst online interface ever. Grades tough on exams and ensures you solve things in only one way or else it is marked wrong. If you never took Calc in high school you are thrown into the pit, good luck.

This class was hard and the professor didn't really do much to help. He was okay I guess but not anything special. Sometimes his lectures were really confusing and he just couldn't figure out how to explain it in terms the class could understand.

He is kind of rude and disrespectful. Doesnt give the best help when needed.

Decent professor for Matrices. Creates his own note packs and walks through them in class. Makes you purchase WebAssign for assignments and the textbook. There are two exams (kind of difficult...) and the final is in two parts, so you need to make sure you do good on those and complete all homeworks in order to get a good grade.

I have taken multiple classes with Dr. Riel at Behrend and he is my favorite professor on campus. His lectures are clear, he is quick to answer questions, and if he makes a mistake he recognizes it and does everything in his power to fix it. He is the best professor I've had here and I plan on taking another course with him.

Took Stat318 with him over the summer. Can come off as a bit rude at times and is quite nit-picky with grading.

Dr. Riel is a great professor who truly cares about his students. He answers every question thoroughly and always makes sure everyone understands the material. He answers emails very quickly. The exams were representative of the in-class and homework problems (watch the videos and attend office hours!) I cannot say enough good about the class!
