Have you reached out to the school? That you can’t access it doesn’t mean it’s gone. You took the classes; they need to be reported.
Would your chances increase with a 1500+. Yes but that means little. No where here is UPENN admissions and statistically you will not get in.
Again, try and see - don’t over analyze here - because no one here can give you an assurance either way - only Penn can.
Spend your time on building a varied list and not focused on - will I get in or not.
Penn or Marshall - you can become a nurse and impact lives and work at the top hospitals.
