What does the curriculum look like? Is it like in college where there is organized material that an instructor plans beforehand kinda like an individualized class approach for a class, or do students just show up on the spot?

There is no set curriculum like in college but instructors generally have a theme for the week. Classes a much more fluid, moving at the pace of the students. All you have to do is show up. You will always get something beneficial.

Curriculum! Best of the best techniques
