Reviews of professor Karol Lang

Rating: 4.0/5, difficulty: 3.0/5
I agree with those who say he is getting unnecessary hate. Professor Lang gives opportunities for extra credit and cares for his students. He provides plenty of resources for you to pass from posting his lecture notes, clicker question, equation sheet, extra credit opportunities and his availability to answer questions. He does his job well.

 probably the most challenging class i have ever taken in ut. not only is he a bad lecturer his homework is so much work plus everything you put into this class is worth nothing at the end of the day. even having attended all office hours and done every homework and quiz nothing helps. if you have no background in physics DO NOT TAKE HIM.

Dr. Lang is well versed in physics and respected. His hw's prepare you for the exam. He is available to help those who seek it and provides plenty of opportunities to do well in his class. Professors are not meant to be you babysitters try and remember that when you write a bad review.

Lang has a very old-school humor. This made it difficult to ask questions during lectures sometimes, but you can tell he has a passion for physics and he cares about his students. He gives some extra credit for Instapolls during class also. The homework is more difficult than the exams but if you can understand it, you will do well in this class.

Dr. Lang is very sarcastic and has a dry sense of humor, but that just makes his lectures more enjoyable. He's clear about what you need to know to do well on the exams, and if you understand the "classic problems" from class you should be totally fine. The homeworks were harder but you could get help from the TAs every day so it was fine.

Dr. Lang is a very knowledgable man and you can tell he enjoys lecturing, but when asking questions he has the, "I don't understand what you're asking me so I'm gonna make you feel stupid" thing down to a science. If you feel confident in your physics skills I would take him, but if you're someone that needs more help, he's not the one.

If you've taken AP Physics in HS then you should be set and I recommend him. But if you have no background in physics or only took normal level or even honor physics in HS then Lang's class can be really difficult. He is funny, but that's about it.

Engaging lectures. Tests are similar to homeworks - you have to work in his class but getting a good grade is possibly

tests were hard imo. grade was like 30% hw which was helpful bc they were quest and ta's would help solve them. lang was a terrible lecturer imo, he expected everyone to have a pretty good basal level understanding of physics going into the class when most of us did not
