i didn't do the paper, just saying if (140-8x)/4 was what u put as ur answer, its not in simplified form cause (140-8x)/4 = 35-2x sorry if i misunderstood you as i don't even know the question, its just answers should be simplified

(140-8x)/4 = 35-2x i didn't do the paper but i think u have to simplify fully to get full marks for any question

the conics poly's and volumes in the CSSA was sooo easy then every harder 3u question was like death integration and complex and graphs was ok

arrrrgh i finished 7/8 questions in cssa 4u in 2.5hours and couldn't do anything in the circle geomtry for the remainder...

i don't get circle geometry either, i find it harder than mechanics or conics... so screwed when i get to harder 3u

2u -> coroneos 3u -> fitzpatrick 4u -> either cambridge or fitz depending on the topic

whether its hard or not doesn't matter cause its all scaled relative to ur cohort

i think thats quite a high estimate, IPT rank 5/17 is about the 30th percentile in the school, but the school rank isn't that high, eng ext 1 is also 50th percentile in a low rank school. modern and ext history are good scaling and awesome rank, but its also hard to tell if that rank is a...

Re: Trials fail = goodbye band 6? whoa! is 6 pages meant to be low quantity? i've never written that much on any essay ever!

how do u know ur HSC mark?

i did the rate of decrease of intensity of light in torches over periods of time with varying brands of batteries, it was expensive but it was an easy one EDIT: oh yea! go energizer!

some people may disagree but imo: school and uni: 80% work, 20% talent competitions: 80% talent, 20% work what makes u suceed more in life is ur work though. u will achieve better marks at school, better at uni, and employers will not go for the lazy even if they are extremely gifted. so if u...

Re: How did people go in the maths comp today? i did the stupidest thing, for the question like (x^2+x)^2=(x^2+x)+... i actually worked out the solutions but i didn't read "what is the sum of the positive solutions" and read instead "what is the number of positive solutions", i was rushed and...

Re: How did people go in the maths comp today? i had no idea how to work it out so i guessed using approximations, i found the area of the circles and approximated the areas of the answers, 3 of the answers i think were below the area of the circles and 1 was like 4 times the area so there was...

Re: How did people go in the maths comp today? i don't think it was either if that was to work for all fn(x) cause f0(x) had 2 solutions to it same with f1(x) and f2(x) though it looked so simple i wasn't sure

i can't say on business as i haven't done it engineering mostly like a more demanding version of physics, in terms of quantity of material covered and mathematical ability on the understanding of concepts level, they are about the same, it contains some elements of chemistry when doing...

Re: 回复: Re: Changing/Dropping School? really?! how does it work? i'm almost certain in all but 1 or 2 subject that my external is gonna be higher than my internal

i hate it when they teach us the wrong things...

if u do 2u and its ur worst, it simply won't count, only the best 10 units count, the only disadvantage of doing extra units is the time it takes away from studying other subjects i mean by percentile, how well you perform relative to the rest of ur class or ur ranking, it may be harder to...
