I’m doing my m3 test tomorrow and one thing I’m worried about is If I multiply it by 3.14 instead of the pie key and get a slightly different answer , in the mark scheme do I still get it correct? The other thing is if I get a long decimal as my answer what do I round it too?
Hi, good luck for tomorrow! 1) In terms of using 3.14 instead of the pi button, I would always recommend using the pi button as it is more accurate. The only exception being if you are told to use 3.14 in the question. 2) If you look at Q3 on the Jan 2020 paper on the volume of a cylinder. The answer was wanted to at least 2 decimal places. 1696.46cm^3. Look at point viii on page 3 here ccea.org.uk/downloads/docs/Past-Papers/cleared/GCSE/GCSE%20Mathematics%20%20%282017%29/2020-January/Standard/0/GCSE-Mathematics%20-504-January2020-Higher%20Tier%2C%20M3%20%28With%20Calculator%29-MS.pdf
Hi in my m4 past papers and mocks i seem to do very well but it all goes to waste as the last questions (usually 7 marks) i can never do my gcse is in 5 days i was just wondering how i can improve
It’s great that you’ve done well understanding everything. Watch tomorrow’s video (1 Day to Go) and I give some tips… it’s normal that the last questions are tricky, but try to apply whatever maths you think you should and be sure to show your workings. By doing this, hopefully you’ll get it right but if not, you may pick up method marks. Also look at the grade boundaries, you don’t need to get everything right to get the top grade in M4. Good luck
Hours sat in a class room and nothing. 5 minute video and its all fallen into place. Great video thanks
Dude do you know what? your smart
Thanks very much 😊
he is a math teacher
i just wanted to say a huge thankyou! you have helped me out so much! Thankyou!!
thank my teacher hes giving your channel our school
Cheers got a test tomorrow
Thank you great explanation and thanks for keeping it short and concise not deviating
Thank you very much!

Wow amazingly explained
corbett maths be big brain
Thanks
Thanks 😁
BIG BRAIN TIME 🧠
For the formula would 2PiR(r+h) work?
From a quick look, that seems correct too... just factorising 2pi r^2 (area of the two circles) + 2 pi r h (curved surface) 👍
