One of the great things about taking classes as an adult, as opposed to taking them as a high school student, is that you get to have more control over how the information is presented to you. If you are someone who learns by doing, you can take a hands-on class with a lot of in-person work. If you learn by listening, you can take a class that involves a lot of lectures. And if you learn best by writing and doing your own calculations, perhaps a sit-down class in a formal school classroom would be best. There are adult and continuing education courses that fit all of these formats, and we've collected the articles on this site to teach you more about them.
