31 and 1410ish on ACT and SAT, respectively. Honestly dunno what advice to give. Uh... if you know it, it'll be easy?
ACT, you will be short on time. Do not read more than you need to. Do not read the story, read the parts you need for questions. Especially the science portion, don't bother, just interpret the graphs.
SAT is pretty much the ACT with more time and slightly harder questions, so you should be good if you can do well on the ACT. If I remember correctly the math doesn't go above trig, but I may be wrong.
