there is a document posted on that page
Thank you! 😄😄

This is from a physics formula sheet, can't remember how much if any is required for C2
ok thanks
3. There is a 2016 news item about calculator use here:
http://qualifications.pearson.com/en...ies&pageTypes=

It doesn't say anything different from the 2015 version, but it's got this year's date on it if you need to bring it to the attention of your school.

ok thanks
Area of triangle
Area of trapezium
Area of circle
Area of sector

It's really not that difficult.
possibly if you don't know how to use those identities well

Dunno, everything bruh, everything, there's nto that many topics to cover so cover them all.
Depends
Most likely harder due to the turnout of this year's C1 paper

really? but it's just free marks
trapezium rule is can you use your calculator and formula on the formula sheet?
the other one is can you integrate and sub in x for numbers?
loooool I know C2 isn't difficult in general, I'm just listing some examples off the top of my head that could potentially be a topic for discussion. Different people may face difficulty in different topics, so that was quite a sweeping statement there.
6. whats the conditions for a point being a point of inflection?

First and second derivative is 0 (for a-level)

Further to A-Level, you need to verify that the third derivative is not 0.
8. how many ums is c2 again ?? and what percentage of the whole A level ???

Ah alright thank you so If we were asked a question and the first and second derivative was 0, we could conclude that it's a point of inflection without having to verify the third derivative?

Yes,

logs+ geometric sequences can be a pain if rearranging and taking logs of stuff is difficult for you

100 ums
The whole A-Level is 600 UMS so C2 constitutes 17% of the whole A-Level
14. What kind of hard questions can there be for Binomial Expansion?? I dont get those questions that ask for yu to estimate stuff after solving it. Im so scared guysssss!! And do u guys think Solomon papers are worth doing?

the estimation questions require a substitution for the value of x.
Eg If asked to expand (1+3x)^8 and then asked to estimate (0.97)^8, ou need to work out the value of x to put in the expansion.
you can do this by doing 1+3x = 0.97. Rearranging gives x=-0.01.
You put this in the expansion to give the estimation

thank you so much ur a life saver

Just go through the Physicsmathstutor model answers but don't scroll down to the answers

I'm revising all of C2 in about 4 days up to Saturday night, which leaves me Sunday+Monday+Tuesday = x3 past papers/day = x9 past papers in total.
^ Regular Edexcel past papers: Jan 2012, June 2012, Jan 2013, June 2013, June 14, June 15.

Edexcel IAL past papers: June 15 IAL, Jan 2016 IAL.

+ x1 Madasmaths hardest difficulty exam paper.

I need to to get 100% in C2 as badly as I need to get 90% in C3 + C4 (ideally I want 95%+ in C3/C4)
That's exactly what I need after the C1 exam
