Sounds like you didn't read the question
Prescribed + related qualifies 'variety' imo
I think those who wrote 2 should not be 'penalised', but should not have their 2nd text marked, I would have killed to use my 2nd text but was forced to adapt my 1st into something longer.
Damn I feel...
It's a mini essay. Quick thesis, two paragraphs of new analysis, quick conclusion. Weight the insights/theis/conclusion about 1 mark, and 4 marks for the techniques.
Just did 2008 Ext1 and got 77/84. I didn't fully get out the last two parts on Q7, and made some very bad mistakes graphing, got the binomial wrong as well. I'll have to do better ;)
2005: 91/120 --> 76%
Q1-5 I killed, full marks. But dropped 14 marks on questions I couldn't attempt, and the rest was part marks lost. Only one 'silly' mistake!
Take it SLOW. All my mistakes are because I skip steps in the algebra or miscalculate fractions. A missed negative sign in resisted motion means the whole thing falls apart!
I often start questions too soon as well, rushing into a circular geometery question or probability one and having to...
On 1999-2004 I get in the 90-100 range, highest being 98/120. I am learning not to rush Q1-6, and make no mistakes since I usually don't get very many marks on Q7 and 8 anyway.
This wont work sorry, just like gurmies said
"Your method fails to acknowledge that 135792468 is a possibility...as is something like, say, 821345796"
I might be wrong but:
[4^5 + 3^5 + 2^5 + 1^5]*4! = 31,200
Chose a place for 1, there are 4 spots as you have to allow room for all the...
Phew, I got a big mess as well! Something with In(root3 + 2), thats all I remember. And thanks for the solve on the z^5 question...I didn't think complex unity would even apply :(
