This is undoubtedly one of the best tutoring channels out there! Thank you so much, we all owe you a lot! 👍🤝 ( hope you reach at least a 100k subs, you really deserve it!)
Love the way you explain each question so thoroughly. This really helped me revise for my mock in 2 days. I was struggling with the angles one but know I understand it thanks to you.
for Question 6, I've looked at the mark scheme and it doesn't accept £7.21 as the lowest possible selling price. Im not sure why but the correct answer is £7.22
It's best if you look at it as an inequality.. Because you have to earn MORE than 80K.. so you're essentially solving for an inequality instead of an equation..
Hi Sir, For question 8 I substituted the 2 angles into cos but I put my answer as 0.8 and -0.799. Would I still get the marks or would I have to write +- 4/5?
