I realize you have to take the FOI exam and the subject test for basic ground instructor, but what are the prereqs for doing that?? Thank you everyone, as always.

It's possible, but ther's probably no point unless you have a job lined up as a GI.
The FAA written tests are not really great learning tools, so you may not gain a lot of additional knowledge by taking them.
If you are going to get yout CFI someday you will have to re-hash all that stuff anyway for the oral part.
