Mega A Level Maths Thread MK II

Thank you! I'm trying to relax, I have biscuits to help with that, I just hope I don't get confused between East and West like I did on one past paper Silly mistakes get me every time...

I feel you, I feel you.

Well I wouldn't be fooled as its the only one that you can't use a calculator in, so most of the silly mistakes will mainly be arithmetic ones, so just make sure you're extremely careful when answering the questions

cheers mate,really appreciate this you too for the f321 and your other exams ps if you still need help then I'm free for f321 - just haven't gone on here for a bit - also do you know what the rough mark is on C1 for 100 or 90 UMS ?

I didn't realise that Edexcel hadn't made the markscheme yet

Yeah, doesn't help that I've got 46 questions to do tonight as they're due in tomorrow and I've left them until now, not too good really :-/

I always am.

Just happy to help really and I've been attempting all questions so far and got them right, I've got a mock this Thursday too but I'll let you know if I need some assistance and sorry but I'm not too sure, maybe someone else would be able to given you a rough answer.

but hey the silver lining is you don't have exams tomorrow!

and you can always just say that you've done them but forgot to bring them in, to just buy some time. BUT GET TO IT!

The problem is the number of possible alternatives a lot of questions have. For example, take this question (From Edexcel C3 Jan 2013):

Find the exact value of $(sin22.5+cos22.5)^2$

The expected method:

$(sin22.5+cos22.5)^2 = sin^2 22.5 + cos^2 22.5 +2sin22.5cos22.5$

$= 1 + sin45$

$= 1 + \frac{1}{\sqrt{2}}$

The method I used:

$(sin22.5+cos22.5)^2 = (\sqrt{\frac{1}{2}-\frac{1}{2}cos45} + \sqrt{\frac{1}{2}+\frac{1}{2}cos45})^2$

$= 1+ 2 \sqrt{\frac{1}{4}-\frac{1}{4}cos^2 45 }$

$= 1 + \frac{1}{\sqrt{2}}$

(A note to be taken from this. No matter how crazy your method is, if it's correct and a specific one hasn't been asked for you can't be marked down. I like to think that reading this on my paper made an examiner somewhere laugh.)

Well I've actually got my M1 exam tomorrow, so yeah should be fun and I can't do that as I feel it's wrong to lie, I'll just start them in a little while and surely they can't take too long

Okay maybe no silver linings for you. Good luck tomorrow! I did mine in Jan, 96 UMS because I'm a boss (mostly just hardworking)

Yeah, but it's my own darn fault really, so I can't complain that much and very nice score! I'm hoping that I can get 100 UMS or something incredibly close to it!

On TSR, getting 100% in an exam seems to be the metaphorical equivalent of joining the mile high club...

I'm not sure if I understood that correctly, isn't it appreciated on here?

Was that genuinely the first thing you thought of, or were you bored and trying to find an alternative solution?

Anyone got any last minute tips for AQA C2 maths exam? (Got it tomorrow)

Also, I've done all the past papers from 2005-2013, are there any other papers I could use? Tried finding extra logs questions on google but had no luck :/

Solve the simultaneous equations.

Urgh, I'll wait for half term


Simultaneous equations!

a = 25 - 25r

(25 - 25r)/(1-r)=25
Etc
