# Mega A Level Maths Thread MK II Watch

1. (Original post by justinawe)
Surely it's too easy to be an IMO question? Unless proof by example isn't allowed for some reason.
I would've thought proof by example wasn't allowed if it's an IMO question.

Ok, that is ridiculous This thread regularly goes off track because people throw around AEA/ STEP level questions but this thread is not for IMO-level questions - very few people on here have the prerequisite knowledge/ training to attempt questions of that standard....questions like that belong on the proof is trivial thread
Oh god I told you that it was an IMO question to just let you think of a better way of solving it than proof by example. It's not actually an IMO question, one of my friend just gave to me to try and answer it so I just posted it here. He did give me the hints that I just told you.

I'd have thought that anything mathematically legitimate would be allowed in the IMO

I was joking it didn't really offend me!

I still wouldn't try to even it out because I may have made a silly mistake somewhere in the paper

While your question is pretty much redundant in real life, to answer the real question - "would you pick 95 or 96 UMS if you had a choice".

If it made no difference grade-wise, and I had all 100/95 up to then, I'd actually pick 95 for the novelty of having round numbers for all maths modular UMS that might not make much sense but I'm just weird like that I guess

However, if the streak was already broken, so to speak, I'd pick 96. If you'd asked me before results day for the Jan exams, I'd definitely have picked 96.
*phew* scared me for a sec
True True, Imagine ending up with 94 because you try to even it out! Yeah I agree, I like lovely round numbers but if it was broken i'd choose differently
I got 111 ums in chem so far, aiming for 129 so I get a lovely 240 UMS=A

Sowwy.

There's no such thing!
LOOL, I guess so, but you know what I mean * apologies for my foolishness*

Meh, who knows? It may earn you like a point, but I guess to get 7 you'd need the general result

Lol I'm just kidding. There are some horrendous equations out there

111 out of? Don't you have to do a practical or something?

Good luck
My god I've got a quadratic inside of a quadratic that I need to square root, this seems a lot more challenging than I first anticipated

LOOL, everyone's saying that to me today, getting me paranoid for no reason

111/150, I done unit 1 and the practical, I only got 61/90 for the exam in Jan (I spent my time going out/eating instead of prep) and 50/60 for the practical
11. After all those rounds of exams fp1 seems like a complete pushover, just finished matrices, and previously re-visited coordinate geometry, numerical solutions to equations and complex numbers, it feels like C1.2
12. how would you integrate x(x^2 +5)^1/2 using the substitution u=x^2 +5
i know it's integration by substitution, but i keep getting it wrong help

It's a fairly standard example.
If you post some working I can spot a mistake

They'd have specified in the question if that were the case... if I were a participant, and they didn't give me a 7 for a proof by example, I'd make a formal protest, Sheldon Cooper style

It is a 1 module... Good work!

nuh, it's (x+1)/2 not x + 1/2
does that make a difference?

I can only imagine it being something horrific really

A very slight difference: instead of 1.
