Not too easy. Not too difficult.
Filloux is an excellent teacher. Her class is different from other professors but she explains all her concepts really well. Instead of memorizing, Filloux's class is more about learning material that can be applied to solving many problems. To really understand the course you need to do the lecture problems she posts.
The material that really stood out were curved arrow mechanisms and chair structures. We also did a lot of M.O. diagrams and classifying different types of isomers.

Advice for students:
Make sure to do the lecture problems. They help understand the concepts from lecture and give good practice. Also go to lectures for the clicker points.
