Your scores are pretty good. You want a good final estimate do nbme form 7... Its the latest form and said to be quite good. Although all the nbme forms are pretty good, form 5 has generally been rated the easiest of the lot and 3, 6 and 7 the most representative. Search this forum and you'll find many many comments on which form is best and what it all means.
I'd go write it though, your scores are consistent with a high pass.
