Really good professor overall! His examples are super helpful and well explained. Ochem is challenging so don't expect otherwise but if you attend lecture and read the book, everything is pretty straight forward. He has his TAs take roll in discussion so be prepared to go every week.

I took Professor Harran in Fall 2010, for Chem 30A.

Overall, fantastic professor. He has powerpoints, which are honestly useless, but his notes, examples, and presentation are excellent. He expects quite a bit, as his exams are analogous with those of Dr. Craig Merlic. So if you want good practice, simply study Merlic's exams, and you will be a-okay. Office hours are great, though at times he may get a bit impatient. However his office is posh, so that may be a motivator - overall, a great professor, with a passion for organic chemistry.

Exam Averages: 1 and 2 around 60, final around 55.
