Reviews of professor Ji K Seung

Rating: 2.0/5, difficulty: 5.0/5
Professor is passionate about physics, but has a lot of homework every week, along with lab reports, and a quiz every week. Hard quizzes and tests. I didn't feel like he explained things well sometimes, kind of got me more confused. Sometimes I'd ask him to clarify things and would refer me to the book. 
He's nice and you can make up hw.

Mr. Ji was awesome anyone who didn't pass his class was is lazy. There is no easy physics class but Mr. Ji is caring and will help you and answer all your question. He will let you correct your homework after handing out solutions for full credit! Same for the lab reports and also he curves the grade at the end (That's almost 30% free grades).

Professor Ji is one of the best professors I have taken he truly cares for his students and is always available when you need help 24/7 His lectures are long, gives quizzes pretty often and lots of hw but he is a fair grader and lets you resubmit work to increase your grade, so an A in the class is not too difficult.

One of the kindest and most helpful professors on campus. Professor Ji always stays hours after class answering questions and helping students. Getting an A is pretty doable. Just complete every single assignment for full credit and do a LOT of practice problems before the tests and quizzes from openstax (mostly), the textbook and ilectureonline.

Professor Ji is the most caring and patient professor I ever had. It's easy to communicate with him outside of class since he provides lots of office hours where you can ask him questions and he'll be happy to assist you. Do the assigned homework to do well in weekly quizzes/exams. Make sure to complete all labs since it's a huge part of your grade
