study something you like and can actually get you a job (Maybe Oral health therapy? its related to dentistry, but like if u r in it for the money just do something like compsci or whatever lol) in the event you don't EVER become a dentist (this is just the reality as it is still very competitive) and then resitting UCAT, maintaining a high GPA and interviewing etc. Also, consider taking the Post Grad pathway i.e taking GAMSAT as well.
