Junior year madness!?

So, i recently recieved my PSAT scores. They do not match my GPA in anyway. My GPA is roughly around a 90-92. My PSAT score was a 1230? What do i do!? I'm planning on going to a cl and doing this 8-week prep plan cosisting of making 1000 vocab cards and practicing math questions, critical reading questions, grammar questions. Do you think i'll be ok? I want to go to The College of New Jersey or a pretty good school.
