Studying can be defined as looking over stuff you’ve already learned for the purpose of “locking it in.” Like studying for a test. You’ve learned the material, you’ve used the reference works, and now you need to exercise that knowledge to make it stick. That’s studying, and that’s what this area of our site is about.
There’s a whole folder dedicated to study resources, rather than the single page dedicated to learning and reference resources, because effective studying can include interactive presentations of the information you are studying and we need a place to put such interactive resources. The other two pages aren’t interactive, so they don’t need their own sub–site. ;]
