When to take ACT and SAT

I’m currently going into my junior year and am confused on what to do. I want to take both the ACT and old SAT but I want to do enough prep for both since I’m aiming for 2000+ and 30+ and can get the testing over with before senior yar. I just found out that I’m busy for the April and June days for the ACT.

Should I take the old SAT in November and the ACT in September or ACT in February?

Take the ACT in February. That gives you all summer to study for SAT, and then some. You can also do some light ACT prep in this time. After that, put your full focus for the ACT in February, including winter break. Unless you think you’ll have to retake, which is possible, then take the ACT in Sept, study for both SAT and ACT in the summer, more focus on ACT tho. Then focus on just the SAT. That will give you enough time to consider retakes if necessary.
