Not too easy. Not too difficult.
I would recommend it because, unlike the lecture portion, you are hands on and sometimes one on one with the teacher with some pretty difficult things to understand. There's no such thing as too many questions because that is you time to ask them.
The highlights were definitely seeing the things you were learning about, its one thing to hear about all the color spectrums but to put on glasses and actually see all of them is something you can not fabricate and/or forget.

Advice for students:
Understand that there should be a good amount of note-taking simple because you've probably never heard this before. Ask questions, assuming is not bad because some things are review but the chances of the topic focusing on that singular fact are slim. Use all the time you have. You are allowed to leave early if you finish one task, and the rest is homework. However, you also can stay and work on that and ask questions about it then, because the class only meets once a week if you have questions and getting ahold of the teacher is a problem, you'll get behind.
