Great guy, very down to earth and will help you with anything you need. I see students in his office getting help all the time. Would highly recommend him

Dr. Winiarz is the best! He knows his stuff and is a good listener and good speaker. He is very approachable and is the same open minded, friendly, helpful person every single day. Quantum chemistry is a tough class and Dr. Winiarz expects alot, but if you want easy then you shouldn't be studying chemistry.

Hardest chemistry class I have ever taken. Very good teacher but the material is extremely difficult. Almost impossible to keep up with taking notes. Homework is extra credit which helps immensely. I was thrilled to get a C.

This is one of his first years teaching the General Chemistry 1 class. He's a great lecturer and teacher, but he tends to run late in this class and you'll find that not all of the material on the homework got covered in class. Really nice guy though.

Mr. Jeff Winiarz, what an illustrious man. His love for chemistry is unrivaled except for his love for vodka. This surprisingly doesn't affect his teaching capabilities in the slightest. This God of a man will drill into your head the importance of fudge factors and plugging in the numbers and doing the math. 10/10 would take again, love you Jeff.

Great chem professor. Really funny dude. Made the class actually fun. He's laid back and chill. He's really working that Dad-Bod. Saw him at the Locker Room once; so you know he's cool.

Jeff is hilarious, has a good taste in music, and he organizes his knowledge based on whether or not information is intuitive to him. A wonderful professor.

I always enjoyed his lectures, though the tests can be tough. As long as you show up to class, do the homework, and study for tests, you should pass this class.

Textbook isn't necessary, but comes with access to the online homework. Lots of homework after every lecture. Make sure to go to LEAD to get bonus points and practice!!! Didn't always get through every lecture, but what he did get through, you would know very well. Great professor and really fun during class.

He is amazing in class, but hard exams

This class is pretty difficult if you don't put in the time. He recently changed to multiple choice tests which make it very difficult to get exceptional scores. They also make you do a lot of unit conversions to mistakes are certain. He is a pretty interesting guy though, and despite some of the hate he got, taught the material very well.

His lectures get sidetracked often and his class can run over time. His grading system is great and allows for students to miss class or fail an assignment a few times without failing the course.

An amazing professor. Showed us pictures of his trip to Africa throughout the semester. I'd definitely want him again if my major allowed it.

Jeff is passionate about what he does. That means you get to be passionate about a ton of recitation and class homework too! This class requires a Chegg account unless you want to spend 6+ hours a week doing solely Chemistry homework. Tests are very detailed and tough to get a good grade on, but recitation and homework will carry your grade!

Jeff may be the single greatest Chemistry teacher in existence. I left my full ride scholarship at Harvard just so I could take his General Chemistry course.

Great professor. Really knows what he's doing most of the time, and knows how to get you the info when he doesn't. HW is rather heavy, but it's all good info.

Jeff is so funny and nice and teaches coherently. The material is a little hard if this is your first chem class but it won't consume your entire life trying to get an a. lots of clicker questions in person and online that are pretty easy if you are paying attention. I loved this class and professor.

Jeff was a great and charismatic teacher. His class was enjoyable even in an online format. Many will say he gave too much homework, but I think it's the right amount. It's perfect to reinforce the topics learned.

Jeff explains everything very well and uses relevant examples and figures to help explain during the lectures. There is about 1hr / night of homework as well as the clicker questions and recitations. If you go to class and pay attention, the exams aren't so tough.

cool dude

Requires you to actually do the homework and reading and there's kind of a lot. But there's also extra credit and helpful TA's if you're lucky, so it's not hard to get a B if you put in work. People complain about the class because it takes a lot of time and work to do well but it is totally doable to get an A.

this is the third time this week ive had a 2+ hour homework assignment from this man

I went to lead to do my homework every week and plenty of helpful TAs were there as well as Jeff himself. You could ask questions, and they would explain it to you. I think people underestimate how much studying you will have to do. This is college, its definitely the hardest class for a freshman, but just put in the work.

One of the best lecturers I've had. A lot of work outside of class but as long as you do the homework and study reasonably well for the exams you'll end with an A.

Unfortunately, Jeff rating gets tanked by freshman having a hard time with the college transition and blame the difficulty on him. The homework is long, but students that struggle shouldn't be spending less time on the material. Go to LEAD, get the easy extra credit, reach out for help, and I'm confident you'll get an A.

Professor Winiarz will give you all the tools to succeed you just have to use them. He doesn't hand out an A, you will have to actually work for it. After the first test he even says that your grade is not based on your intelligence but on how well you prepared. However you only need a 40% average on the exams to get a C.

Winiarz is disliked by many because the class asks for actual effort. As long as you don't chatgpt the homework and show up at recitation, you'll do fine on the exams. His lectures are deep and comprehensive and usually include some brainrot memes from 2009 that (ironically) are funny. Lots of resources exist if you want to do well. Use them.

People hate on Jeff for no reason. Yes, his class is difficult, but that's because of the material, not because of him. You can get away with not going to LEAD ever as long as you go to recitation and pay attention/ask questions there. His tests are tough but not impossible, and reading the textbook is important for this class.

tough grader but if you put in effort you'll pass

Very tough class but very effective professor.

Class is difficult, but if you actually apply yourself and pay attention you'll do great. He rewards good study habits by encouraging LEAD attendance and provides lots of great study material. Very reachable outside of class and really wants you to succeed. His class also gives you a good feeling of what to expect here at S&T.

Recitations sucked and Prof. Winiarz assigns lots of homework, but what are you gonna expect. Took this course as part of an 18 credit hour first semester and all in all, it really wasn't that bad. Just put in some effort and you'll get an A. It's only general chemistry after all.

This course was in a flipped classroom style format which is really not conducive to student learning in my opinion. Spent roughly 7-8 hours a week studying, doing homework, completing recitation, and watching pre-recorded lectures. Despite this, Prof. Winiarz is a solid professor that definitely wants his students to succeed.
