It really depends on you, whether you're really committed or not coz a fast track degree is sort of like an intensive course, which in your case they cram everything into a two-years course. If you're the kind that don't fool around all the time, then u could try it out. But do bear in mind that your holidays will be compromised as well, meaning u might have to study even during the holidays.

I'm currently doing a 3.5years one and based on what I'm learning right now, rushing to finish my degree would not be a good idea. There's a lot to learn and if there's no holidays, i'll die lol..

Besides, y would you want to do a fast track degree? It might help financially, but i dont think it'll do any good to your uni life. You might have less time to spend with your friends since you'll be studying and doing assignments most of the time(i think u would?).
