Yeah, it seems like you could definitely take 1st place next year. Good luck in doing that :)

That's a giant gap between the top and middle of the class. At least you know you've got a good ranking in the bag for the HSC.

I was the opposite, though my prelim was hard. I was doing past top 10 school papers when I'm at a rank ~300 school, so even though everybody else in year 11 found the test hard, it was nothing compared to any of the past tests I did lol. So I did pretty well I reckon. No mistakes that I saw.

Just did Extension Maths, way easier than I thought. Prelims for me are over :) (even though I only had two)

I've got your new question, though are you sure it isn't (x-u)^2+ (y+u)^2 =2(1+u^2)? http://m.imgur.com/MmuoPz5

It's that drop in physics rank bro /s It's probably just because the estimates are just rough estimates.

I can do 26, 27, and 28 (a). I don't exactly know what they mean by perpendicular form of the line. Here are my answers: http://m.imgur.com/a/99DpH

I wish this wasn't true.

I'm not too sure whether my answer is correct, also I'm not exactly sure what the question is asking for. I think that the angle the either the biggest it can be or the smallest it can be can keep getting infinitely closer to 0° or 180° (As if it is >180°, it will no longer be a convex polygon...

I'm guessing he means perimeter, as the perimeter of the square would be 20mm.

Re: Year 11 Mathematics 3 Unit Cambridge Question & Answer Thread You're not the only one.

Yep. At least year 11 doesn't count, just gotta eliminate the stupid mistakes for Year 12.

Wow that second one though. I've lost a mark in year 10 physics for something equally stupid, I did 3/2 m/s^2 when the teacher said it wasn't right as it should be 1.5 m/s^2. WTF! But I'm in the exact same position as you, 2 marks lost all year. First test 100%, then lost a mark in the next two.

Nope I always make 1 silly mistake. Last time this was what I got wrong: a+b=-3 Sub in a=2 2+b=3 b=1 I'm so angry at myself for forgetting the minus sign.

I'd say that someone who is great at math is more likely to be much better at mental arithmetic than the average person, but it doesn't mean that they are good at mental arithmetic.

I didn't mean do the whole general course in his own time, rather maybe learn the financial maths topic, which I'd assume is important in some commerce areas. Obviously the large majority (99%) of his study should be on his subjects he chooses but if he really wants to do a commerce degree that...

I had my 2 unit test today, I finished with an hour to go and I'm pretty sure I'll get 100%. Now I just have to study for Extension 1.

Well he can see how he goes in year 11 and make the decision whether to pick up extension or not next year.

I have a different solution to everyone here, my answer: http://m.imgur.com/nXOg1g8 That's what I love about geometry, the variety of ways to solve 1 problem. Also sorry for bad handwriting.

Basically for ii) the question is without replacement, James isn't going to go back to a level he has already searched. For iii) it is just the probability that he will search the wrong floor first for 5 days in a week. As the chance he will choose the right floor is 1/3, the chance he will not...
