Hey! These videos are greatly appreciated by me and my study group. I have been struggling with measures (limits of accuracy etc) I hope you could create a topic test video on it as it would greatly help me! :D Thanks Mr Tompkins!

It always helps to hear your thought processes as you try to tackle the questions, especially Q4, which required a great deal of effort for just a miserly 3 marks! Why are AQA so parsimonious and Scrooge-like with their marks? Are they all ex bankers? Bah humbug! Throw another log in the fire and fill up our mugs with marks! Garçon!

Hello Mr. Tompkins. I would like to start by both, thanking and congratulating you because your videos are really brilliant. Please do not stop releasing them. About question 4, couldn´t we decompose both numbers and find the answer by multiplying the found prime numbers to get the multiple of 3? 180= 2x2x3x3x5 ---- 750= 2x3x5x5x5. In both sides we have 3x5 which gives us the 15. It could maybe make it a bit quicker. All the best and thank you, again.
