The math section is mostly addition, subtraction, fractions and percentages, multiplication and division. There wasn't any geometry or any other kind of math. Just basic algebra.
The reading section was all passages and then some questions about the passage to follow. There weren't any grammar
corrections to be made or anything like that. And the passages were all about science and history, so I think that's how they integrate the science part because there wasn't an actual science test. Just math and reading.
Susan - I got pretty much the same scores as you on the practice tests so I didn't worry too much about the math. And I did ok on the actual math part of the test so you should do fine.
I got to the school about a half hour early so I sat in my car and skimmed through my book before going in. The night before I highlighted all the sections that I felt least comfortable with and I reviewed them quickly in the parking lot before the test which really helped out alot! So there's a little trick for you!
