<p>Yeah those should certainly suffice. Meltzer’s Grammar Guide in combination with “How to write a 12 essay in just 10 Days” took my writing from a 700 to an 800, so there’s no reason the same thing can’t happen for you. I would probably take it in October of next year (maybe November) if you are doing the Subject tests in June. You could take it in May; however, this gives you very little time to prepare, so I would not recommend it. Take it in October or November because that way you’ll have the entire summer to really focus on preparing for it without having to worry about AP exams. Good Luck!</p>
