I took the TEAS test last week. Although I did well on the test, I'm not a fan of standardized tests. The math questions were mostly metric conversions, algebra, fractions and decimals. The science was really broad and in no way did it seem that it could gauge your knowledge of A&P, Chem or Physics. The reading comprehension, spelling
and grammer were pretty basic.
I think the only part you can review is the math. It's all concepts you already know, but probably haven't used in a while...ex. dividing fractions, multiplying ratios or algebraic equations, etc.
Good luck on the tests. I think it's about 3.5 hours long, so if you can, bring a granola bar and take breaks if allowed.
