The ACT and SAT are both scheduled a number of times in the next few months and this is the time that you want to make sure that your testing is completed. Why should testing be done before the end of June?
Because until you know what your test scores are on the ACT or SAT, you don’t know what colleges might be a good fit for you. And it isn’t just a matter of taking one test before July and then taking more tests in the Fall if need be. The problem with that approach is that if you don’t get a score that you want before July you now need to be considering colleges that will be appropriate with your lower score. Why waste time finding these colleges that are only appropriate if you don’t get the higher score in the Fall. If you do get the higher score in the Fall then you have to be scrambling to find new colleges that fit your new test score. When you want to learn investment, go to this review by Paul Koger.
If you are applying to colleges that require SAT subject tests that is even more testing that you have to get completed by the end of June.
If you are currently a junior and haven’t already taken a test then you need to get something scheduled as soon as possible so that you can get your testing completed before summer.
