I appreciate your efforts over these years. I am moving onto Year 12 next year and I feel reassured looking at your videos right now and I definitely won’t be leaving any time soon

Keep it up! 🙌🏼

Hi Sir, thank you SO much for these videos. Are you planning to cover the options for further maths (specifically further mechanics 1 and decision 1) or just pure? Thanks

Hi Sir, could you clarify if the Casio FX CG50 calculator is allowed in maths and further maths A level exams, and would you say it is worth buying?

Hi sir, I know it's not related to the video but I'm stuck on a geometry problem. How could you prove that sin(x) + sin(x+2pi/3) + sin(x+4pi/3) = 0 for all x?
My first intention was to use the addition formula for sin, but that seems like a bit of a "plug and chug" approach. Is there a geometric way of proving the result?
