Hello my friend—yes, you can apply to some great places. While you wont be in shape for a top-5 school, you should be okay within the top 20 or top 25. Just be sure to look at places that are interested in entrepreneurship, international experience, etc. Haas, INSEAD, and IMD come to mind—schools in Europe (connected to London perhaps) will not hold your age against you either. Hope this helps!
