Edexcel A-Level Statistics & Mechanics - January 2019 Mock set 1 paper 3 exam walkthrough (new spec)

A full walkthrough of the January 2019 mock paper 3 statistics and mechanics A-level maths edexcel exam

Timestamps:
00:00 Q1 stats from a frequency table
13:42 Q2 correlation coefficient
22:10 Q3 conditional probability
38:40 Q4 hypothesis testing
49:50 Q5 binomial distribution
1:00:35 Q6 speed time graph
1:10:47 Q7 ladder question (yep one of those horrible ones)
1:22:35 Q8 vectors
1:29:56 Q9 velocity, trajectory of a ball through the air
1:40:33 Q10 pulley mechanics

Corrections:
Ignore some of my statements about venn diagrams for q3. Clearly I misstated independent and mutually exclusive. Apologies.
Mechanics question 2 (b). My final conclusion was incorrect. µ is actually inversely proportional to the distance of the centre of mass to B. so as the centre of mass gets closer to B, µ increases. My reasoning was correct, I simply misstated the final conclusion.

Last month I left a comment in one of your videos thanking you for helping me revise for my mocks that I sat in January. My results came in last week and I got a 9 (I expected an 8 or lower). You’re amazing!

Omg I needed this for evidence for my a levels you literally saved my life man 😂

Hi, I think there's a mistake at about 1:21:48, increasing the distance between B and centre of mass will reduce the co-efficient of friction, as you said when you reduced a to 1/2a, the co-efficient increased.

Thanks! watched so many of your videos.

Could you do a set of A-Level further maths papers please? I’m getting like Es currently so I definitely need it

[reddress]

Thank you, thank you, thank you, thank you, thank you very much.

[daniorga]

the supervisor claims mean time is less than 16 min. and it is indeed: 13 min. so, he is right

[GP-eqgh]

I find stats hard, even after doing the book questions I struggle.

1:52:36 Why is the acceleration gsin(theta) if the diagram shows mgsin(theta)? Where did the m go?

[ahmedjahed]

Have you considered doing any gcse further maths videos?

[crypticgod]

Do you also know what papers are locked at the moment which you can be able to share? Is there any specimen sets which haven’t been released to students like specimen set 2019/2020? Thanks once again

[lgs]

Can you go over any Core pure and applied fm papers for further ? If so which applied further maths modules can you do ?

[RedSteelNima]

Hello, do you have the grade boundaries for these papers ?

[crypticgod]

Thank you. Is it possible if you can email me the mock set papers for 2020 so I can practice ?

[roshinimano]

Hey how would you work out the normal distribution on a casio fx-85gt plus calculator?

[tuition-matetuition]

Hello, may i know the software you are using to write on the pdf
