Dr. Hong tries to make Chemistry harder than it should be. He's very hard to understand with his thick accent--making it even harder to learn chemistry. There is a ton of work for this class, as if it's the only class you're taking. The lab that goes with this course is also demanding as far as work goes (C125).

He's a good professor, but very tough when he thinks most bad students are slackers. I took it the first time with another professor at iupui, and got a solid C and failed miserably but attended all classes, but I took it in the summer with him scoring the same and also taking the lab which I should have only taken one thing and got D.

Dr. Hong really wants his students to succeed. However, his lectures aren't the greatest and is hard to understand. He posts additional videos that just made me more confused. His exams are terrible, half multiple choice and half free response and oddly the multiple choice were harder. His class is curved which is nice but expect to fail the exams.

He has very helpful office hours, and is always willing to help. He is obviously very passionate about chemistry as well. Organic Chemistry is a tough course, but Dr. Hong made it manageable.

He is an OK professor. I never attended a lecture, you are better off watching the pre-lecture videos, reading the text book, and looking at other resources.

CHEM-C341 is one of the hardest classes you will take at IUPUI, but it all depends on the amount of work you put into it. Go to every lecture as there is 6 points of ex credit if you go to class and Dr. Hong hints at possible exam q's. Exams are hard, avg around 50%, but class is curved by 10%. 25 MC q's and 75 points of short answer.
