Some colleges are test-optional and still accept standardized test scores from tests like the SAT or the ACT. The application process is very competitive, so students may consider taking a test prep course or studying independently to apply with their best possible scores.

It is common for applicants to sit for an exam more than once to improve their scores: some take both available college entrance exams to determine the score they want to use in their applications.

Curiously, students often receive advice or feel pressure to take these important tests without preparation. But because good scores are so important, then surely they are worth studying for.
