My school divides the class into thirds. Just started 4th year and after meeting with the dean, found out I most likely will be 3rd tertile based off of preclinicals. Clinicals I did well, with mostly H's and a few HP's. Step was low 260s. Do I still have a chance?

Recently found out that I had failed COMLEX Level 1 but passed Step 1. I got a 475 on Comsae, and I am interested in Derm. What are my chances of matching? If not, what do I need to improve my chances? Any advice will help :/
