Study Strategy
I printed out the Preparation Manual from the ETS website and took the practice tests. Then I went through the entire manual and highlighted any terms I didn't recognize. I used some Khan Academy videos to brush up on Math and memorized all the grammar terms I could find.
Testing Strategy
The test was easier than expected. There was no Calculus in my Math section and Social Studies was mainly Economics and Texas History. A calculator tool and a page that shows Math formulas and the periodic table comes with the test.
I took my break after the English portion and then completed the three shorter sections.
