How should I prepare for SAT and ACT at the same time

I am taking both the SAT and the ACT this upcoming October. I have the blue and red books, and I have been doing practice problems from one book one day, and from the other the next day. Do you guys have any other effective study stategies? (I am aiming for 35+ and 2300+)

My D prepared for SAT in one month and ACT the other month over the summer before junior. There is no problem in preparing for both at the same time. Just make sure you don’t confuse the guessing rules in the 2 tests.
