Peter has gotten a lot better since last year, I had him this fall and he improved a lot this quarter, especially with working out problems in class. His lecture slides are online and downloadable and should probably be looked over before coming to class. The first midterms and final was manageable, although he might try and trick you so be careful

I managed to earn an A on the first midterm, an A on the second midterm, 101.7% on the hw and ended up with a C+ in the class. How? God only knows. The final was all multiple choice b/c no graders were available and the average was very low. However, Peter curves the extremely low grades and disregards the high grades.

Weiss is probably one of the nicest teachers I've ever had. He really cares about every student succeeding and provides a LOT of resources for them. However, he's a very hard tester. No note sheets allowed, and any small mistake on a test will get you marked down. I did worse in this class than 1A and 1B, despite it actually being easier.

He'll spend a lot of time working out math problems, since that's what the majority of chem 1C is (it's the only class he teaches). He cares a lot about teaching, and isn't just here to do research. He's hard, but not unreasonable. Focus on the equations and study.

Professor Weiss is definitely one of the better professors I've had so far. He really knows the content and can explain things well whenever you have questions. I wish I had taken his class on-site but I still enjoyed taking CHEM 1C remotely with him. His class is still challenging for sure but you can do well if you work hard enough.

Based on the grading system and the amount of resources you can really tell he wants all his students to pass unlike some professors. You get lots of attempts on homework and two on tests and quizzes, so just do them and youll be able to get a good grade. Was able to learn without the serious stress like in other classes. 10/10 would recommend!!

Great Professor! I took the class online with him over the summer, there's video lectures, chapter quizzes, and homework on webassign. All of which have ranging from 2 to 5 tries to ensure everyone does good. His pre recorded lectures were helpful and everyone is available to help you succeed in the class. Definitely recommend for Chem 1C.

Great guy and a really fun class. Goes out of his way to make the class enjoyable and engaging. Doesn't communicate the material very well. Doesn't prepare you well for exam questions. Test questions are fairly simple if you pay attention to the lecture. Video quiz questions are nearly impossible without Chegg. Buy Chegg for your grade being > 80%.

does not grade, gets everything automatically input with webassign. Lectures don't correlate w/ the webassign work at all, hw and tests were a guessing/cheating game. Does not prepare you at all for any of the actual graded work. Lectures are long but online so attendance not mandatory, in class lectures are interesting but not helpful.

He was a great teacher and very understanding.

Peter Weiss is the first professor whom I felt like he genuinely cared about his student's success and learning. He is very transparent with his grading and what will be on exams. Most of the grading is exams and completing ALEKS, which is not too difficult if you are on top of the material. It was seriously a pleasure to have taken his course!

Peter is the most understanding professor I've ever had. I can fully admit that the C+ I received was due to outside circumstances. His grading scale makes passing a lot less stressful and he's very understanding. Lectures have really cool demonstrations. Homework is worth the largest portion of your grade, so just be sure to complete the ALEKS pie

His class on air pollution was interesting and understandable.

He's helpful when you require assistance, and I easily made friends in this class.

Easy A, asynchronous. Has some interesting topics, but the lectures are from a previous professor (boring). About one discussion post a week, open note midterm and final. There were also "Mandatory discussion section Zoom meetings" for extra credit. If you are looking to focus on major courses and just need an easy class, take this.

He also let us use an index card for the quizzes. Attendance for discussion sections was mandatory, and there was also ALEKS hw, but it was manageable.

Professor Weiss is a great professor and teaches you everything you need to know for exams. Aleks can be very dumb sometimes, but personally I felt like quizzes are easy and barely needed to study.

He is a great professor who cares about the subject he teaches. Try to sit in the front and be attentive. He tends to get tunnel vision and not call on people to ask questions in lecture so have some patience when you raise your hand.
