Not necessarily. There are a number of aspects to look at this. Yes, USMAPS need a NOM to enter WP just like you. NOMs are given out to those who (with this in mind) will finish and graduate at a SA. This is why you find the best academic resumes win NOMs. I don't nor do you know how well the MAPS student finished. They do have to meet academic expectations. In others words its not a given. Your NOM source could have two slates available. Just stay the course. If you are not selected, what is your Plan B and continue to work it.
