For context me and my father made a deal that if I get a 88 Atar I Can study where ever I want in Australia to get out of Canberra. From this I want to study in Melbourne or Sydney, however my Year 11 estimate was a Mid 70s. Is this realistically plausible? Can I jump 14 points from 74 to 88?

Please no sugar coats, I understand if its not plausible then its not, but I need to know as I am unsure on how it goes. Last year I was averaging 70s and some 80s but I can definitely achieve much higher results.
