on a scale of 1-10 how hard would you rate P2 and P3 against P1???

With 1 being equivalent and 10 being rediculously hard in comparison to P1...

P2 - 4
P3- 7/8 (kinda depends on how easily you pick it up and how much you work at it)!!!

i would agree with that (leaning towards the 8 on p3 ;p )

but then again, having done p2, your maths skill will be better by the time you get to p3

I found Pure 2 fairly easy and Pure 3 fairly hard. So, perhaps Pure 2 = 3/4. Pure 3 7/8. Like the last person!

Yeah, I don't think P2 is that bad. The calculus in P3 is the hard stuff; although I personally found it more interesting.

P2's fun, P3's a hassle. Hopefully I can get 80+ in P2, 60 in P3, easily beating the A threshold.

The scale is confusing - from 1 to 4 seems a larger increase than from 4 to 8 geometrically.

I've already collected my nice 80+ in P2 so I just need to retake some AS exams to get the B's to A's and A's to good A's. This should mean that I can properly screw up P3 and still be fine!!!

I just remembered. Pure 3 (for our board anyway) has the stupid comprehension paper. They seem to be either really easy or really hard. But, theres very little maths involved. Its just sometimes too wordy, although they are nothing to worry about because they only carry 10 marks.

P3 is only 1/6th of the A level, meaning if you do very well in the others you could get an A without actually learning the P3 syllabus!

Though not a wise move if you want to do maths at university.

Which is why I need to properly go over the binomial expansion and vector geometry...

Binomial expansion... eugh. Seems so "messy", probably because of the unfamiliar notation.

What is it again, something to do with n/(x+n)!+n!...

(1+x)^n = 1 + nx + (n)(n-1)(x^2)/2! + (n)(n-1)(n-2)(x^3)/3!......
|x| < 1

It's nCr really, n!/(n-r)!r!, that to me is the easy part to figure out.

Say you have 7C4, then you have 7!/3!4!, let 4! cancel each other out and you get 7*6*5/1*2*3, which is 7*5 = 35...

But that doesn't work for P3 when you have fractional indices or negative numbers! How I hate series questions...

binomial expansions was in our P1 syllabus!!
General expansions was P3.

For OCR P2 is about -5, its way easier than P1 and P3 is about 6, its quite a bit harder than P1

I think P3 is quite hard especially in my school
I did P1 and P3 together at the beginning of Lower 6th. That was really a disaster!!! I couldn't understand the P3 stuff at that time as i had no knowledge of either P1 or P2!!
And the teacher always say don't worry, by the end of L6th you are able to do all questions and everything will make sense to you. That's quite true!! But i had a really hard time at the beginning of L6th.

And now when i am having my P2 lessons, i found it so boring. The teacher need to explain the things in detail to the people that haven't done P3..

So i think P3 won't be that hard if you have learnt P1 and P2
