Grade: N/A

This class is not hard to get a good grade in, but it's very frustrating for those who actually want to understand the material. Lectures seem to jump around and unevenly emphasize content, though I appreciated the recaps. We either spent too much time on complicated derivations or extremely basic problems, rather than the applications more suited to an introductory-level class. Many generous policies made up for the resulting poor performance.

this class made me switch my major (biochem) LMAOOO to be fair, i did not put in enough time for the class, but even then, there is sooo much content that you'd have to have a prior chemistry background to fully understand what he goes over.

you don't really have a choice if you're in stem, and must take this course, so my biggest advice: throw away ur social life and grind chem!! jk. but fr go to office hours bruh

Honestly this class was tough but worth the struggle. The class has asynchronous lecture videos and problem solving sessions during actual class and discussion time. Quantum is inherently difficult but Professor Barr, Pujan (TA), and the LA's were always available to help us answer any questions we had during class, outside of class, and office hours.
