One Hour Revision - Edexcel GCSE Higher Maths Non Calc Questions 9 - 15

This video is all about the Edexcel sample assessment - issue 2 and forms part of the playlist on of One Hour Revision materials.

The whole idea is that you can download the paper, try the questions, and then view the solution. The video is around 20 - 30 minutes long but, by stopping and starting, you should be able to spend about an hour trying each of the exam questions.

The video deals with questions 1 - 8 and covers the following topics:

- standard form
- indices
- pressure / force / area
- mathematically similar shapes
- box plots
- percentages

I hope the video helps and please do leave a comment - thanks!

Your method of calculating quantiles is the CLEVEREST THING IVE EVETMR SEEN

17:09 if you look closely his highest is on 28.25 when he should be on one line to the left as 1 little box is 0.25 you can figure this out by finding the median of 25 and 30 which is 27.5 then do 27.5-25 which is 2.5 which is the value of 2 big boxes then half that to get 1 big box then divide it by 5 as 1 big box is five little boxes long getting you 0.25 then because we know the median of 25 and 30 is 27.5 all you need to find out is how many little boxes it takes to get to 28 which you show as 3 when in reality it’s 2

DOES HE DO IT ALL WITHIN ONE TAKE? legend

On q14b Why isnt Sam more consistent he got a higher score I'm so confusedd (18:30)

[armandolaci]

For question nine we could divide 900 by 60 and then just multiply by 10 000....its a lot easier...

[priya]

On q14 (18:35) if you have a lower IQR and Lower Range does that mean you are more consistent?

[abbzy]

For question 9 isn’t the first answer supposed to be 27X10to the-3?

[MAXmaxsutherland]

11:20 dont you have you move the 0’s 3 times across backwards again since you timesed the top and bottom by 1000 already

[shabnammalik]

In number 15 I gave an example eg normal price of a tv is £100 and showed the reductions and answer of £56. Is this ok?

[potatoyama]

for question 10a) dont you have to write 8 or -8 or is that only for when you solve for x?? pls i dont wna lose marks

[crazyratlady]

This is really helpful thankyou,
All I would ask is why do you change the symbols in question 11? You swap the times and the divide around and I really don’t understand why. 😿

[HeataveGaming]

Just to point out, Q10a you said the answer is 8 when it is actually +8 or -8 the marks wont be given if you dont have -8 but thanks for the video

[luma]

On question 15 I wrote Mary is incorrect because the TV set is reduced by 20% THEN by 30% so you find 20% of the tv price then 30% of the reduced price. Would I still get the marks?

Please can you kindly assist in making a Foundation Paper too.

On Q14 (15:46) If you have drawn the numbers right but, instead I went up in fives so 5, 10, 15. Does it matter what you go up in, and does it matter if your box is smaller.

[abbzy]

For q15 why did you multiply 0.7 and 0.8?

[juwayriyahmalik]

hello, for question 15, how did you get o.8 and 0.7
