Not too easy. Not too difficult.
Prof. Halpin is a wonderful, but strict, teacher. He make the class a lot of work, but by structuring the class with additional peer-tutoring and recitations, the information becomes much easier to understand. He also somehow manages to turn a large lecture hall into a smaller classroom by offering opportunities for questions before, during, and after lecture, along with his convenient office hours.
I now better understand the basics of chemistry (a class I had hated in high school), and by the end of the semester I didn't mind waking up at 8am to go to class. This class has taught me, outside of the course material, to grow used to a structured class everyday of the week.

Advice for students:
Make sure to buy the notes and to do ALL the homework, along with all the practice finals. You do NOT want to walk into those midterms/finals without any practice problems underneath you, as Halpin has a way of combining many topics into one to make sure you actually understand the material.
