Choosing a class

Some of our subjects are covered in multiple classes, and the titles alone will not tell you which one is right for you. These pages walk through the choice: who each class is for, what you are expected to know already, and when the honest answer is a shorter course than the one you were about to book.

If none of them covers what you need, tell us what you are trying to do and we will point you at the right class, or tell you we do not have one.
