What would be the best route for me?

I took the ACT in Sept. and i got a 27. I THINK this was a fluke score as I was consistently scoring 32-33 on practice tests all august, but during the test week I stayed home sick from school and was anxious on the test morning. These are 2 of my ideas for testing:
Plan A:
-Study for the PSAT using Khan Academy and other online resources
-Take the ACT again in December after studying this fall to see if I can get my actual projected score of 32-33, if I don’t I’m done with ACT
-Study over Christmas break and throughout Jan, Feb. for school provided NEW SAT in March using specific study books (ie. pwn the sat math, Erica Meltzer’s books) and take again the next fall for improvement if needed
Plan B:
-Study for the PSAT using Khan Academy and a PSAT book
-Take the CURRENT SAT in Nov. after buying a generic studying book containing 10 practice tests
-Continue studying, but with pwn the math sat etc, and take the free school provided NEW SAT march
-Take the ACT one last time depending on SAT scores received.
