Carrot, I think you can guess why pretty much noone at all (except jzhang of course) is posting, everyone has probably fallen into an intense depression and low self esteem today LOL

I wasnt there, but I can say with certainty I'd get above 40% lol. Just had a browse thru the paper.

You may want to post solutions for this.

How does everyone think they went?

The main problem was time, if I was a little faster I reckon I could of done a lot more, I got 0/5 for conics (the good outcome of this was that I learnt that something called the 'reflection property of ellipse' is actually in the syllabus), 0/3 for probability missed the 4 mark volumes, but everything else was mostly fine, maybe a few 1 markers here and there gone somewhere due to sillies, or proof is not strong enough

I did better than I thought I would.

That doesn't mean I did well. I skipped the entire conics question and major chunks of other questions.

Cool . Yeah I figured that if I did this myself in exam conditions, time would be the biggest issue.

 

[twinklegal19]

skipped most of Q15 and Q16, both due to time + I had no idea wtf was going on

Also got trolled so hard by Q11 lol
