You can use your UAI/ATAR for up to 5 years. But personally if i were going to leave it for that long, i would do open foundation or something equivalent. But back to your question, yes your ATAR will still count next year.
As far as decision making goes, don't worry about being indecisive...
Mum caught me wanking over sex scenes on that show "queer as folk"... I tried to do this with the volume turned down, but it got harder to cover my tracks...
The basic physiology of my parents... My mother is taller than my father, and in addition, my father was submissive to my mother... I also have unresolved issues with my mother, which lead me to an inevitable attraction to other guys... My first time was in the back of a toyota echo...
the fact that you are being defensive leads me to believe that you are gay... You probably tell your parents that you are straight, and only have relations with men....therefore, you label yourself a "bi"... dude just be yourself =)
