A score send that has not processed can sometimes be stopped in MyACT. A send that already reached the college usually cannot. This is not a void and not a registration cancel.
If it already arrived
Assume the college has it. Score Choice still lets some campuses ignore a date: which dates to send.
The bottom line
Stop an unsent report in MyACT if you can. Do not count on un-sending a score a campus already opened.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
