New Grad, NCLEX SOON

Hi everyone,
I have been reading this board for a few weeks now, I graduated May 17 and have been doing lots of NCLEX questions. I am waiting for my ATT and hope to schedule my test before I start my job July 5. I have been doing Saunders, ATI, Mosby and just got NCLEX 3000 today. I have been averaging 70's on all the practice tests. I was a B+ student and on my ATI predictor it stated I had a 99% chance of passing my boards. I will continue to do practice questions. Can anyone give me an idea of what scores are realistic when taking these practice tests?

Thanks so much.

Denise, GN
