Not too easy. Not too difficult.
The class provides a daily systemic distribution of homework with a class discussion on that assignment the day after. The textbooks covered a through review on the subject. The educator would leave time for individual class discussion. He had a full understanding of the subject, his own experience and would answer any question a student suggested.
It was engaging. There was independent discussion on the subject.

Advice for students:
Do your homework consistently. Study for the tests no matter how much understanding you consider yourself to have. Do the practice tests at the end of each section to practice for the test. Participate as much as possible. There is some math to be expected, not calculus level but simple algebra. Be sure of your units and graphs.
