I'm an IMG, studied and did the exam while pregnant, it was HARD.
I heard that if you score more than 70% in the free150 you are good to go, and when your nbme scores are under certain number they are underpredicted. So I didn't have a choice and did the exam as scheduled, and I'm very happy with my score. Good luck, you ALL can do it.
