How to Raise Your ACT Composite Score
Whether you look at your ACT score online or wait to get it in the mail, the biggest number on the page is always the composite. While admissions officers will certainly see the individual scores of all five tests — and their subscores — schools will use the composite to evaluate your application, and that's why it's the only one that matters in the end.
The composite is an average: Let the full weight of that sink in. With an average, do you need to bring up all four scores equally to raise it? Do you need to be a superstar in all four tests? Should you focus more on your weaknesses than your strengths? The answers: No, no, and definitely no.
