A-level Mathematics 2018 Exam Specimen Paper 3 - Statistics and Mechanics Edexcel GCE

This is a walkthrough of an Edexcel A-level statistics and mechanics specimen paper from 2018, used as a mock paper in preparation for the 2019 exams. Timestamps are in my pinned comment below.

Time stamps:
00:00 intro
0:59 Q1 (frequency table, continuous data)
23:58 Q2 (correlation coefficient, hypothesis test)
34:00 Q3 (binomial dist., normal approximation)
56:20 Q4 (venn diagram, probability)
1:09:58 Q5 (normal distribution)
1:18:33 Q6 (vectors, suvat)
1:24:13 Q7 (Find time given velocity vector, force, and mass)
1:30:26 Q8 (mass pulled up a slope)
1:44:26 Q9 (beam in equilibrium)
2:01:18 Q10 (tennis ball hit over a net)

Apologies for the drilling noises in the background of some of the video. I think the neighbours are doing some renovations or something.

Also I don’t really like how I explained question 9, I might go over that again separately in another video.

from 1:48:00 onwards how can u take moments when theye both acting clockwise?

[cheyennekou]

How come for q9 we don’t do forces up = forces down? As in Tcos30=20g, why doesn’t this work

[yousufabrar]

it was very helpful sir. Just a slight thing could u be more transparent about those directions i get really confused

[george.s.adderley]

Could you explain the logic behind npq for the standard dev please.

@ 53.33 do you need to quadratic formula ? do u loose marks if ur just put everything in the calculator?

Why do you drag these videos out? Could get through this paper in 30 minutes easily

[alannabrown]

How come during the normal distribution in question 2 you didn't need the critical value for the hypnosis testing, you just used the sig level of 0.05 ?

The long-waited piece of art....ehhhh....MATHS ! Hahaha ! 😂

Will the statistics questions in these past paper videos be useful for my a level statistic Edexcel exam in June? There are no past papers so I'm going through these ones.
