Is PWN the SAT Math enough? Do I need to get Dr. Chung's Math book addition to Pwn the SAT?

I am scoring about 600. I really need 800. Should I finish Pwn the Sat first and finish Dr. Chung’s Math? Should I get both? Or is just PWN the SAT Math enough?

Got 800 with PWN. Think it’s enough.

Don’t get Dr. Chung. PWN could be enough. If you want more, get something from either Dr. Steve or Philip Keller.
