I'd say practice tests first. If there are any programs that interest your daughter, then maybe have her take it for fun just to see. I did that in middle school more for taking a challenging test than for a program, but it helped when I wanted to do different programs and to try for dual enrollment at college. It's been a while since I took them, but Princeton Review and Kaplan put out a lot of accurate tests for the GRE and MCAT. Might be worth looking into for ACT/SAT prep...
