Princeton Review/GRE: correlation between scores

[MB37]

To those of you who have already taken the GRE - how well did your real score correlate with your practice exam scores? I've done very well on the few I've taken so far (>1250), so I think I'm ready to take the exam. I'm just a little afraid of getting a surprise when I walk into the real GRE. I also have the Barron's prep book, it only has one practice CAT GRE and I haven't taken it yet. Thanks in advance!

Didn't anyone use Princeton Review to study? I did even better on the Barron's CAT exam, so I'm starting to believe I'm ready to take it - just would appreciate some reassurance from people who've already been there if possible. If not, I guess I'll just have to go ahead and register...
