He writes poor tests IMO. Still, pretty easy. Be sure to do well on quizzes/reports. Go over previous exams since he reuses questions. Lecture is sorta pointless since he writes notes on the slides and puts them online. If you need help with spectra, ask your TA

Wasnt a big fan until going to office hours. Nice guy! Hard class.

Hypocritical. He gives you four different websites to reach him but if you prefer real live help and cant make it to his office HOUR you are out of luck. Not being available to help while simultaneously appearing reluctant to do so are not positive qualities..

Justin is a good teacher. All of his material used in lecture are available on-line but you should still go to every lecture. He knows what he's talking about but he also knows that you don't know. Read the text on the spectra if you really want to understand it, otherwise the class is pretty easy.
