Hey wayfarer701,
Just wanna offer my two cents as someone who matched into a top PM&R program and my number 1 choice. I struggled in med school, had to remediate a class, and also scored in the low 200s on Step 1. My test scores were consistently below average, but I got rave reviews from my clerkship directors because I was enthusiastic and got along well with people. My advice would be to continue being yourself and letting your enthusiasm and personality shine. PM&R is a field that emphasizes "fit" much more than test scores and grades. If you have a program you want to match into, try to do a rotation there. Make sure to have fun and get to know as many people as possible. PM&R programs understand that candidates are much more than their test scores, and ultimately a program wants someone who's trainable, dedicated, and a joy to have around.
With subpar test scores and grades, it IS possible to get into your dream program!
