ACT & SAT Prep

ACT or SAT? Most students score noticeably higher on one of them. Take a short diagnostic of each, and Test Match puts both results on the official ACT/SAT concordance to show which test is worth more points to you, and why: your math and reading on each scale, and whether the ACT's faster clock is costing you. Then prepare for the test you chose, with a plan that runs to your test date.
