Chem 147 is pretty chill. The quarter you take it really depends on your guest speakers, Winter 2018 had some really cool speakers and then some horrible ones. The class is pretty relaxed though, its a good networking seminar and I'm glad they host this. This quarter we had Clarke, Spokoyny, and Paul Weiss hangout and bring guests over. The only work required is to make a resume and cover letter, which holds practical value if you put effort into it. Best of all they feed you.
