Answer the easy math questions first, and after going through the entire section come back around to do the hard ones. I guessed randomly on many calculus problems that looked too lengthy (ones with complex integrals, trig identities, optimizations, etc) and still got a decent 85 in math. Word problems are good ones to come back to later since they require you to interpret the text.
Sometimes plugging and chugging the multiple choice answers into problems works well.
The calculator they give is time consuming to use so try not to rely on it. Getting good at estimating and mental math helped me a lot. Math is the last section of the test and I was brain dead by then so I had to use the calculator a couple times lol.
I saw a lot of algebra (polynomials, piece wise functions, systems of equations, inequalities) and basic calculus (derivative/anti derivative). Couple basic stat questions like probability, calculating standard deviation, mean, median, mode.
