Taking the ACT is crucial, but do remember to keep track of your college application deadlines and work backwards accordingly. You wouldn’t want to schedule your ACT test when you’re swamped with extra-curricular activities, examinations or taking up a summer job. Pick a test date that allows you to be fully focused during the preparation. If you intend to re-take the ACT for a better score, make sure you have enough time but do keep in mind that the ACT can only be taken 12 times in total & retaking too many times would suggest poor planning on your side.
Remember, the ACT is only one component of your college application. Colleges would be taking into account your school grades, co-curricular activities, leadership roles, volunteer work, references, and application essays when they consider your profile for admission.
Knowing that the test is offered several times does not suggest that you should delay your application process. Don’t be complacent. Plan early & get going!
