All you can do is apply.
However, my advice is to slow down and get a good, broad educational base. You are currently aspiring to the British system (as I recall) which I think forces students to commit too early to medicine. Medicine has too many doctors with no hobbies and little breadth of interest. They retire poorly and unhappily. At your age you are not looking that far ahead. If you are qualified for one of the early MD programs you will be qualified for regular medical school if it is meant to be. Get a broad education first.
It’s great that you have a passion for medicine. I’m not discouraging that. But you should be aware that our healthcare system, especially as it is evolving now, will snuff the life out of your passion quickly. It is nice to have some extra-medicine diversions to stay sane.
