Not too easy. Not too difficult.
I think that this course teaches students to think through situations practically. It helps them understand how to tell if an answer they have come up with is reasonable or not.
Probably one of the most important things I learned was to keep your mathematical formulas in variable terms and manipulate them to get a final formula. Do not just plug in the numbers from the start. This makes it easy to see if a given quantity is unnecessary. It also makes it easy to assess how reasonable your answer is.

Advice for students:
Read the textbook to help you learn. learn the concepts that apply, not just formulas for specific instances.
