Goodluck mzsheribaby2983! I've withdrawn in the past and did not regret my decision. You have to be ready and as comfortable as possible for that test.
I think it's a great asset for you to "scope out" your test center. Your question is subjective man. Do whatever that'll keep you sharp and energized before the test. Goodluck!
Don't beat yourself up about it. It is a smart decision to take the test when you're more ready and I think it will pay off for you. Thanks, goodluck to you too.
Amazing scores to begin with. I started 7sage mid May and already feel myself changing the way I approach questions. Goodluck on your test; you're going to kill it.
