Bludged first year. Put barely any effort into it. Probably attended less than 12 lectures all up last year, and barely went to my tutes.
I had all the answers for all my subs (to tute questions), put in the least amount of effort I could to get a pass. This will forever stain my GPA. Now I'm looking to do an exchange student program, and I know they take your GPA into consideration when going through the selection process. Also if you plan to overload, you need a credit average (varies for faculty). Luckily I made the cut, but still, i got lucky considering the way i handled first year.
Don't bludge first year, work hard and you'll find out which subs you enjoy more so you have a good idea of what you want to do later on. Furthermore, a stellar GPA is much more likely to land you an interview compared to a mediocre one.
Studying for Uni is way more fun than VCE, so don't think of it as a chore.
