ok, from talking about alevels in my last thread back to gcse's...

I've got 2 real mock exams this week and if I pass it means after christmas I can drop maths and use those periods to focus on something else.. I just need to get a C...

I have been doing loads of revision, been doing fine in my math lessons, but when I do practice papers I can't get a C, I always get a D! Every single maths paper I do I get a D, I have never passed in my life!

And to make matters worse i lose out on ALL my maths lessons next week because we have mocks that week aswell -.-

so basicly, what i'm trying to ask is, is there any other revision techniques for maths I could try? I've done loads of practice papers, written notes, made revision cards, got a podcast thing from my teacher I'm going to do in a minute, read through my CGP textbook... I'll probably read thorugh my maths exercise books to..

But is there ANYTHING else I can do?! I had till Tuesday for my non-calc and Friday till my calc... Any suggestions would be amazing atm

The Mix Honorary GuruThe BBC bitesize website may help you. http://www.bbc.co.uk/learning/subjects/maths.shtml I'm sure if you post the question(s) you're stuck on, someone on here might be able to help you?

The Mix Honorary Gurui'm sure you'll do fine.

i was never that in to maths myself

The Mix Honorary GuruThe Mix Honorary GuruSimultaneous Equations: E.g.

4x - y = 2

y = 2x + 1

What is: X =

Y =

and then,

Work Out 64 1/2

Write your answer as fraction

and another thing is...

Solve 4x + 2 > 3x - 19

Other stuff is at the back of the practice paper with like triangle angles and some weird graphs, but i haven't been taught that because it's A grade and stuff, we've only been taught upto B.

Thanks for the help

The Mix Honorary Guru1) 4x - y = 2

2) y = 2x + 1

You want to make y the subject on both sides, so...

add y to 1)..... 4x = 2 + y

then subtract 2 .... 4x - 2 = y

Now your two equations are y = 4x - 2 and y = 2x + 1

so..... 4x - 2 = 2x +1

add 2 ....... 4x = 2x + 3

take 2x ..... 2x = 3

divide by 2 ...... x = 1.5

now substitute x for 1.5 ... so, y = 2(1.5) + 1 and therefore y = 4

check it. 4(1.5) - 4 = 2 .... this is right, so x=1.5 and y=4

The Mix Honorary GuruWrite your answer as fraction

multiply 64 by two. ...128

add 1 to 128 = 129

therefore it is 129/2

if you want a formula, n x/y = (ny+x)/y

I'm not sure I've explained this very well but I think it's what you're asking.

The Mix Honorary Guruadd 19 to both sides ..... 4x + 21 > 3x

subtract 3x ....... x + 21 > 0

subtract 21 .................. x > -21

this means that x could be -20.99999999, -20, -19 etc

The Mix Honorary GuruIt's still a bit fuzzy but thats probably 'cos I've had a veeeeeery long day,

but i'll look at it again in the morning and takes notes and hopefully it should make sence.. Thank you!!!

The Mix Honorary GuruWhat Grace has said, is how I've been taught.

The Mix Honorary Guruthank you for the help

just the calculator paper of friday now

The Mix Honorary GuruThe Mix Honorary Guruaw thank you i might do at some point, got revision to do now and after school things these couple of days - but I'll probably get horribly stuck on something :P x

Right angled triangles IIRC

The Mix Honorary GuruYes. It's to do with finding out the angle of a right angled-triangle.

The Mix Honorary Guru:yes:

The Mix Honorary GuruI have no time to take extra classes, I've missed all my lessons apart from 1 week this because of mock exams, and I miss tommorows, but I might get to have an extra lesson last instead of technology :thumb:

but yup, i check everything once i've done it a few times

The Mix Honorary GuruThe Mix Honorary Guruwell done :hyper:
