    Can anyone do extension 2 Mathematics?

    Im going to disagree with everyone here, Extension 2 does require some sort of natural ability. No matter how hard you try sometimes you wont be able to get it, and thats the simple truth of it. It also depends on what you mean by succeed since that is subjective. Extension 2 is supposed to be...

    Year 11 Subject selection

    Workload will always be great no matter what subjects you do. In my opinion, if you what to do 4U math then pick Option 1. You will get the generic response of do what you like etc. etc. etc. So I guess you should probably do Option 2. But that means you like Economics because Option 2 consists...

    I dont even know the pressure because Im only doing 4 trials in total hehe. I dont know if you would call it a selective school though, you need to do an entrance exam to pass (a reasonable one too), but for some reason there are still alot of errr, underperformers in my cohort, like really bad...

    2012 CSSA Maths 2U

    Don't get me wrong, 97/100 is good but I feel like its not my mark, as though I dont deserve it. My school just outputs good math cohorts thats all I guess.

    2012 CSSA Maths 2U

    I ended up getting 97 -.- Ridiculous, the fact that I finished the exam in half the allocated time, then pretty much did the exam again (for checking), and I was still able to overlook stupid ass mistakes. And what pisses me off more is the fact that I should of got 100, but got 97 and came...
