AQA Core 2 Maths prep. thread (25/05/16)

Where is 1/5 from?
EDIT: just realised 1/5 is 0.2 lols
Also I put it was a stretch in y by scale factor 1/25 😂😂

I think I got a lower number 😂 crap

I got -1648 ??

-1600 and something (remember exact number)

what did everyone get for the sum of the number of terms?

For the binomial I used the c4 method to fully expand whatever the quadratic was - (2+x)^7 ?

Problem is I completely forgot to times each answer by 2^7 although I did take it out the brackets and write it.

I then used the indices pairings from both expansions and multiplied any thats powers would add to 10.

How many marks would I lose?

The sigma notation from n=4 to 21? I got 90? Did anyone else get that

What did you guys get for the Binomial Expansion last part? I got a negative 4 digit number, can't remember the no. though.

i did the same as you! absoutley gutted, i am alwso wondering how much marks i'd get for it

How did you all find it in comparison to
1) core 1
2) all the past papers for c2??

I think this was easier than c1 but harder than most c2 papers but easier than June 2012 😂But I think it went ok overall

What do we think the grade boundaries will be, usually the average is about 58/59

I did surprisingly bad on the C1 paper, and this was much better personally.

I still messed up quite a few questions like the radian trig one, the arithmetic sum and the area of the sector one.
