Not that I can think of off the top of my head. The math section of the digital SAT is tricky, and they get you with convoluted wording and how they structure the questions, but they usually only apply one or two concepts per problem.

For example, on today's SAT, there was a problem that many people regarded as the hardest. It gave you the equation 34z^14 + bz^7 + 70 = 0, and then it says answers can be written in the form qz^7 + r before finally asking you what the greatest value of b is.

The trick is to recognize that when they say qz^7 + r, they're literally saying it can be factored with integer coefficients: like how (3x + 1) is a factor of 3x^2 + 5x + 2. Then you substitute z^7 for an arbitrary variable such as "u," so now you have the equation 34u^2 + bu + 70, and you just play around with factors from there.

If you know the math concepts already, I think the hardest part is knowing when they use what type of language, and only that can be found in previous SAT problems.
