Why the February ACT Test Dates are Ideal
The biggest advantage of taking the ACT test in February is that you have the Christmas break to study and you have plenty of time after getting your score report to study for a retake on the June test date.
If you are taking the ACT for the first time in February, you should really prepare yourself by at least taking a full-blown practice test before that date. Just the familiarity with taking the full 3 1/2 hour test once before will help improve your score.
Retaking the ACT Test on the June Test Date
About three weeks after you take the ACT in February, you will receive your score report. The thing to do is to look past your "composite score" and focus on the English and Math sub-scores.
These will tell you exactly where you can focus your studying efforts to quickly bring up your score. "Just studying everything" is a very poor strategy that ensures you will work a lot harder than you have to.
Consider an ACT Prep Course
A very good strategy to increase your score over what you got on the February ACT test is to find a short, economical ACT prep course that will allow you to zero in on the exact areas where you need the most help. This will give you the quickest boost to your score.
