I agree with @skieurope . I never suggest my students take the test as a trial run. If your kid does poorly and decides to apply to a college that wants all scores, you might doom her chances. She should practice using real SAT tests, at home or in a library or similar, before she takes the real thing. Often, local libraries or schools will offer mock tests in a test-like setting. That can be a good way to practice.
ETA: ACT is also known for accusing students of cheating if they score substantially higher on a retake, and it can, and does, lead to terrible problems. Don’t take the test, basically, unless you are prepared.
