The Edexcel C2 (24/05/12 - AM) Revision Thread

Not long to go now! How is everyone feeling?

I am dreading it, find it so much harder than C1. Any helpful tips? :smile:

There is never such a thing as doing enough past papers. The more practice the better :smile:

As my PE teachers used to say, "the best way to learn a game is to play it" (and then we'd go and play sports instead of just exercising and drills - yay!)

In this case, as the person above me said, do past papers and practise from books.

This is one of those exams where grade boundaries are really high. So accuracy is everything: you have to do tons past papers no matter how good you are at maths.

The edexcel maths papers are usually easy, so to compensate for it, they probably raise the grade boundaries.

Though i will like harder papers with lower grade boundaries, these high grade boundaries judge accuracy rather than ability.
how would you do

given that

Y=3x^2

show that log3y=1+2log3x

1+2log3x= log3 (28x-9)

1+2log3x= log3 (28x-9)


y=3x2 y=3x^2

Take log3 log_3 of both sides.

y=3x2  ⟹  log3y=log33x2 y=3x^2 \implies log_3y = log_33x^2

Now remember that, logabc=logab+logac  and  logmdn=nlogmd  and  logkk=1 log_abc = log_ab + log_ac \ \ and \ \ log_md^n = nlog_md \ \ and \ \ log_kk = 1

Personally invested in a TI-83 to check all my integration... If it makes it that much more reliable it's worth the extra cash for a fair few marks... These A-levels are for life... Personally I hate differentiation those questions are made by Lucifer himself.

However good luck all!

A good calculator (not banned) that can do various tricks is useful for the exam:wink:

Apparently Edexcel said the January 2012 paper was hard, so will it be easier this summer?
