AQA A2 Mathematics MPC4 Core 4 - 9th June 2015 [Discussion & unofficial markscheme]

haha hopefully! Warwick is my insurance - what a coincidence! what'd need for that and do you think you'll get the grades?

I just subbed in x =3, x =4 etc in g(x) and showed it was decreasing with successive x values. would this get the marks as surely this still shows decreases? :/

Ill just take your A* grade next year when I fail

guys would 68-72 marks in C3 and 62-66 marks in C4 be an A*?

Eek, sorry man! I never thought of it that way. On the plus side, there's more people to pull the grade boundaries down if we all fail, woohoo!I would say that's an A*, yes. That 70+ in C3 could be 100UMS so as long as you have 80UMS in Core 4, you're fine.



That's true. Hey, all the best of luck to you! How do you think you've done?

my method was OE = OB + 1/2 AC or OE = OB + 3/2AC

my friend needs A*A*A*a

That's what i did, it will still get the first 2 marks at least for reaching that stage, I imagine that would be one of the alternate methods as long as you put an explanation.

I couldn't tell you, I'd probably say no as it wouldn't cover all options, however, I may be wrong, I can't remember how many marks that question was worth, like 3? but I imagine 1 maybe even 2 marks for the simplified g(x), I'm not sure how much of a proof you need for it really, although, 1 mark doesn't suggest much

I might see you at one then and that is a coincidence, could you apply for accomadation at warwick. I need A*A*A+step. And nope I really don't think I willi less boundires are very low.

That's an interesting one.. that'll be a high 90+UMS in Core 4 for sure, and I think that'll be either a little bit into an A or possibly just scraping an A.

You'll probably get an A*.

I need A*AA. what'd you need? what course and what uni is your first choice?

Ew
Got put off computing last year with the 120 pages of *******ing coursework + 3 hour exam + writing an actual program (tho tbf that part was good)

yeah i have chemistry unit 4 tomorrow and then physics unit 4 on thursday :/ just hoping in maths i've got at least an A and at a push, low A* :/ who knows?! so worried about it though as it's the one subject I thought i could do really well in

Dude!! What's Computing like at second year? I took it this year and really enjoyed it. I got an A* in my coursework but I'm not that great at coding to be honest, and just managed to push through by working super hard and fixing it little bits at a time.

Will this method work in the second year? Because I really want to take the subject, but I'm honestly one of weakest coders in my class (though I somehow stumbled to 30/30 on my project this year through talking with friends and reading stuff online...).

You only need 90 avg, if you got 100 c3 then you only need 80 and 65 is definitely 80 dude. You've got it.

Yeah I'll join tomorrow, taking a break today!

Yes please do, the only one I'm struggling with is 6 (c) I can't seem to get the second lot of coordinates for E

Imperial Aero Eng, a*a*a. You?

Hahha WJEC?

You think that's a lot? Try 150,000 words in my project this year did a theatre booking system for my local theatre Which exam board do you do?

I do WJEC.

I love computing. It motivated me to apply for Computer Science at Bath. It's a long slog in terms of coursework. I did thousands of pages of work which was ridiculous. Then again, it all worked in the end and I managed 99/100 in the coursework so I'm happy

It was for x>0 so surely by showing that 1/f(x) becomes smaller as x increases it would be proof? I'm not 100% so im only giving myself half marks for that question.

Yeah I should see you at one of them :0 yeah it is! I did, applied to bluebell, arthur vick and some others haha! what about you? WOW thats impressive very high grades!! Good luck i'm sure you'll achieve that if not better when's your next exam?

I think i got 65/75 on core 3 and 64/75 on core 4 :/ need an A* though for uni and don't think that's enough for 180 UMS what about you? bath uni increased my offer from AAB to A*AA a few weeks ago due to high competition! :/ so upsetting as i've so hard all year what'd you think?

Ahh right ok thanks!!
