Why are you already concerned about Uni GPA? you're in year 10...
People are getting more and more competitive, this scares me.
There was a 14 year old on the med-entry (umat practice company) discussions boards.
Ooh, kids these days! When I was in Year 10, I was stuffing my face full of anime and blissfully unaware of any "Maths Methods" or "Specialist Maths"; it was just "Year 11 Maths" and "Year 12 Maths"! And what the hell was "UMAT", anyway? What, you have to do an interview to get into Med? GAAAAAH!
I miss being young, sometimes.
Seriously, though, people really are getting more competitive. I was at the top of my Year 8 class, but I'd probably be fifth or lower had I been in my younger brother's Year 8 class (this year).
