How many times have you walked out of an exam or test and thought "I would do so much better if I could take that test again..." ? The ACT is a test where you can do exactly that. Standardized testing shouldn't be a never ending process. However, unless you scored a 36 on your first ACT attempt, we recommend that you should take it at least once more.
You already know what to expect! The next time you take the ACT, you will feel less anxious and more confident because you know what to expect. This increased confidence will also aid in increasing your score. You know what went well for you, and more importantly, what didn't. There is time to fix the areas where you struggled.
