How difficult is it to get accepted into Premed track at UNC

I got accepted into UNC Biology but not into Honors College. How difficult is it to get into the Bio courses (BIOL 2300) and eventually into the Pre Med track? I heard many students get waitlisted and the Bio/Chem track is extremely selective and OOS students /Honors students get preference. Is the PreMed track assigned strictly based on GPA? Thanks for your help
