Thank you so much for you videos, they are really helpful. As you are probably aware there are not many MEI resources on the Internet. I would be really grateful if you could do an MEI Mechanics 1 playlist, as the exam is coming up soon :)

Hi, is C4 finished now? Trying to get my daughter to look at C3 and C4 as past papers aren't going well.
No chance of a MEI C4 past paper I guess to compare.
Thank you for really helpful resources

what's interesting is that if I switch the signs +26 divided by the square roots of 65 and 14 I get 0.861... I cos inverse that I directly get 30.5 and if I just simply add the minus sign next to 26 being -26 I get 149.5, subtract that by 180 I get 30.5 omg O_O
