Not too easy. Not too difficult.
Ann Valentine was a gem, although unfortunately she did not get tenure and left Yale. If you are pre-med and want to brush up on the chemistry you learned in high school, this is the course for you! I wouldn't take it just for fun, but I did enjoy it.
Highlights were that it was straightforward. No surprises, everything on the syllabus, a fantastic intro course.
