Look at question 4a). It was worth a large number of marks and it was a complete joke. I almost laughed when I saw it.Definately an E4. Anything over 70% is an E4. I'm pretty sure the person who sets the band cut-offs each yr for 4u sets them quite low (usually in the 60%s). I think last yr's paper was fairly difficult though, cause I know a few guys who got E4s and they reckoned they got 71-75/120. But anyway, yes, 71% would be an E4.
how does this let you find a,b,c where (ax+b)/(x-2)^2 + c/(x+4)? Also i dont see how you equated the coeff's of x^2 to get C+1/36=0,It's the "mental method" - a hybrid of the substitution and equating the coefficients (when necessary)
Say you have
Sub in x=2 to . Get this number and write it on top of x-2
Sub x=-4 to , write on top of x+4
So in partial fractions:
If the question contains repeated linear factors, like this:
Sub in x=2 to . Get this number and write it on top of (x-2)2
Sub x=-4 to , write on top of x+4
Now for the number on top of (x-2) I equate the coefficients of x2
So in partial fractions:
Sometimes I use this, but usually the above.
funny that you mentioned that, I thought the exact same thing
Congrats
2006: 103/120
I can't believe I've cracked 3 digits =D. I could actually do the induction, I'm usually shit at that.
Have fun with the integration...Congrats
I'm doing the 2003 paper now - up to question 8 the paper was easy but now i want to kill it XD
hmmmmmm 2005 fell out really nicely for me....got a 116,,,,,i guess the right questions came for me =S lolDid anybody else find the 05 paper fairly difficult?
I managed 81/120.
I got so confused with signs... I guess i should write neatly with signs XDHave fun with the integration...
Wow, are you going for a state ranking?hmmmmmm 2005 fell out really nicely for me....got a 116,,,,,i guess the right questions came for me =S lol
Over 80% i'm pretty sure. But changes every yr - I heard 2006 was hard, and you only needed 60s for an E4.what about for 3u. whats needed for e4 ?
wow solid effort. ive done 04-08 and am yet to break 100. Ill be content with a low e4.hmmmmmm 2005 fell out really nicely for me....got a 116,,,,,i guess the right questions came for me =S lol
well if thats wat ur content with the GO for it xD ....anything extra is just a bonus =]]]wow solid effort. ive done 04-08 and am yet to break 100. Ill be content with a low e4.
i agree,,,,well at least for maths i agree =PCan confirm this. I just did this paper and got 107/120
Those 2007ers were so lucky!
I'm averaging 121/120.im averaging about 120/120
i think thats okay
icwhatudidthar.I'm averaging 121/120.
See, I can make BS up as well.

So who's planning to go hardout on 4u exams the moment you come home from English Paper 2?
I know I am.
