I do not know for sure however I would say that 1. It happened early enough in your undergrad career that you had time to showcase your true ability 2. It is great that you have a dean who is supporting you. If you’re letters of recommendation are strong I’d say that would be likely to consider you. However during an interview they would likely ask you but it seems as though you are willing to be candid and take responsibility. I say you have a good shot!
