I advise for everyone to get the CGP Edexcel Workbook. I was a B/A student and used the workbook when revising for my mocks and came out with a top end A* with 90% on one paper and 97% on the other. I have spent the whole of today rubbing out my answers for when I did my mocks, so just starting to use it again for the real thing. Really hoping I can do as well as my mocks!

Official Edexcel GCSE Mathematics 1MAO/1H (Non-Calculator) Exam Discussion Thread

Date: 4th June 2015

Time: AM - Most likely 8:30 AM

Duration: 1h 45m

Hello and welcome to the GCSE Mathematics 1MAO/1H (Non-Calculator) Exam Discussion Thread (Official). On this thread, you can discuss any questions regarding the upcoming exam and predictions on what questions can come up etc, even though it's nearly impossible to predict the paper. It'd be great if anyone posts revision sources that they use to revise.

Here are some that I've found:

http://studymaths.co.uk/
https://www.mathswatchvle.com/
http://www.examsolutions.net/
http://www.mathsmadeeasy.co.uk/ - Questions
http://www.mrhegartymaths.com/
http://www.themathsteacher.com/gcse_maths.php
http://www.s-cool.co.uk/gcse/maths
http://www.mathsgenie.co.uk/papers.html
https://www.youtube.com/channel/UCBuMwlP7kHkNxdPAqtFSJTw
https://keshgcsemaths.wordpress.com/gcse-maths-takeaway/

Most of the difficult formulaes are given to you at the front of the paper. I've attached the formulae sheet in this thread. However, it'd be great to remember them if you are looking forward to A-Level Maths as it requires you to already know the quadratic formula by heart, and many more.

Some formulaes you need to know during the exam:

Surface area of a cylinder = 2πrh+2πr²
Area of a sector = theta / 360 * πr²
Length of an arc = theta / 360 * 2πr
Area of a segment = Area of sector - Area of triangle = (theta / 360 * πr²) - (1/2 * b * h)
Density, Mass and Volume of any shape
Volume of 3-Dimensional Shapes (Cube, Cuboid, Cylinder and Prism)
Cube = Length * Length * Length or (Length)3(Length)^3
Cuboid = Length * Breadth * Height
Cylinder = Area of circle * height = πr²h
Prism = Area of cross-section * length


Where can i find the gcse maths take away website Answers /markscheme.
if you could tell me where i could find them it'll be greatly appreciated :smile:
Does anyone know where you can find an exhaustive list of the topics that are on Edexcel calculator and non-calculator papers?

I've been looking for a while, but I can only seem to find very vague lists :/
The problem with me is that I finish the paper within 1 hour and I get an A but when I go back to check my answers I don't spot my mistakes. That's what stopping me from getting that A*. My tutor said that this year's paper is gonna be hard. :s-smilie:

The check lists in this document reproduce the topic list from the MathsWatch CD
They are as good a list as any and give you an idea for the grade difficulty of topics rather than grouping them by topic area.
Most topics can be tested on either paper

Hi,

I managed to get up to the cross multiplication bit on the Q4 model answer you have, but I don't understand how you get to (2x-1)(2x+1)(2x-3) as the denominator from (2x-1)(2x+1)(2x-3)(2x-3). Please could someone explain?

Sorry buddy, I didn't post that website as I wasn't sure about it. Someone else had recommended people to use it and therefore I updated it onto the list. However, if there is any question you answered and want to check your answers to. You can only private message me, or post onto this thread / maths section anywhere to confirm :P.

It is all random buddy. There is no way that you can find out what questions / topics are going to come on the paper. The confirmed topics are: Trigonometry (every time) always appears on the calculator paper. Trial and improvement questions are on the calculator paper - they come sometimes (not every time). I hope you get what I'm trying to say :P.

The problem with me is that since 3 months. I've been doing past papers sometimes at home, everytime... I finish in 45 minutes literally and mark it. I never spend my full time, that's why I never read the question and hence I'm flopping. I'm basically not reading the question and I'm losing silly marks - I think I know the topic as soon as I see the question and answer it without reading it lol - awkward.

That's right :smile: - MathsWatch shows the grades aswell. Thanks for posting this :P.

It's all random. There is no way you can either predict an exact topic list of what paper is going to come up this year etc.

During cross-multiplication, you need to make the denominators common in both fractions. In that fraction (2x-1) is already a common denominator. Therefore, you do not need to put it twice there. This is called the lowest / least common denominator. You don't need to write it twice, it's the same thing.
I think you meant (2x-1) and not (2x-3) :P.

Why will it be hard?
The questions won't be similar to the previous years?

I'm guessing his tutor is just predicting this. I don't think anyone has actually seen the paper yet, not even teachers or tutors. Well, I'm not sure, but I highly doubt it. It could be a hard or an easy paper. However, tutors / teachers say it's hard to make the person work harder to get the A* :P.

Thanks and yeah I did mean (2x-1):smile:

So whenever you have two of the same you can just take one out e.g.
(5x-4)(5x+2) (5x-7)(5x+2)
Becomes:
(5x-4)(5x+2) (5x-7)
?

Yeah, that's if you are cross-multiplying like when you are adding or subtracting fractions.
It's similar to a simple fraction. When you add 3/4 and 4/6, what do you do?
You find the Lowest Common Multiple which you use as the Least Common Denominator.

3/4 --> 9/12
4/6 --> 8/12

You add them both together to give you 17/12 which is 1 5/12.
I hope you understand my point :P.

Find out the vector AX in terms of AB.
It shows the ratio of AX:XB = 1:2.
Now find out what is AX in terms of the vector AB.
Use that to find out OX as OX = OA + AX
Express the vector OY in terms of a and b by adding the vectors OB and BY.
Then prove that OX vector (OA + AX) is 2/5 of the vector OY (OB + BY)

After you've attempted the question - post some working out so we can see if you are on the right track.

Yeah, I've been using cross multiplication for a while.but never really came across to off the same factorized denominators.

Haha, I'm not really sure about it :P.
But, I'm 100% sure that you have to do that if it is a case of algebraic fractions. It's just the formula :redface:.
