So I need to raise my GT score, whats the best way to go about it as AGR in a remote area in Iowa?

Which portion are you lacking on? GT = AR + VE (which is WK+ PC)

- Arithmetic Reasoning (AR)
- Word Knowledge (WK)
- Paragraph Comprehension (PC)

If you know your current scores, you can figure out which one is "dragging you down," and then focus on that. Basically go after the low hanging fruit so to speak.

Do you need or project to need a standardized test in the coming future? If so study primarily for your SAT, GRE, GMAT, etc and in doing so you'll boost your GT score as an add-on.

Go to your library and study a SAT study guide. Work hard on it and your score shoot up. Good lick!
