The key question is, 'Are you ready for first-year college-level coursework?' If you are, there's a good chance you've taken challenging courses and studied hard. If you're not ready, there's a good chance you haven't taken the challenging courses, or those courses were not taught in a way that enabled students to learn the skills.

In April, many juniors take the ACT. When they get their scores, they should examine them carefully, talk with parents and counselors, then get extra help from tutors or peer helpers and take courses that will strengthen any academic weaknesses. Students can retest early in their senior year and then report only the score they want colleges to see.
