retake lit or move on?

<p>After getting my SAT results back today, I want to purchase all of my prep books for the october tests soon.
I got a 700 on Literature and an 800 on World History - I do very well in my english classes (I received a 780 on Critical Reading on the SAT) and I just dropped the ball on the lit test
I am taking the math 2 in the fall - should I retake Lit then and prep this summer? Or should I move on to the US history test and aim for another 800?</p>
