    I'm surprised if all your students don't walk out with grades 9s in their maths exam, it's insane how good you are at teaching complicated topics with such sense without using some weird tricks or skipping over parts that you'd think students already know (I don't :D). You genuinely deserve a teaching award or something with how many students you're helping.
    I've been revising maths a lot currently (year 11), as I am not getting the grade I need to do the A-Levels I want (I got a 4+ recently, need a 6 or 5 *at least* ). Not only for understanding the topics, your videos have been really beneficial with motivation too. Something is just really interesting about them. I want to see how far using your videos will boost my grades, lol. Next week I have mocks, not sure if I'll do as well as I want to, but perhaps by the time we get to actual GCSEs I might be. I hope so at least. . . @_@
    Thank you so much for making these videos, without them I'd be revising so poorly and I've already learnt SO much (or getting to know it so quicker) within the first hour of this video.

Thankyou so much, my first paper went so so well and there wasn't a single question that I didn't know how to go about answering and im confident for tomorrow! Every lesson my teacher gives me easier versions of the worksheets because she thinks that I can't do them and she always yells at me in front of the entire class to single me out whenever I don't understand. Can't wait to get an 8!!!

    Problem at c.1.55.20 (B is the midpoint of AC. M is the midpoint of PB. Show that NMC is a straight line). The result follows immediately from the converse of Ceva’s theorem, as follows: (AC/BC) x (BM/MP) x (PN/NA) = (-2a/a)(1/1)(b/2b) = - 1 → N, M and C are collinear. The GCSE Higher is harder than the O levels I did in the late 1950s (Cambridge School Certificate). I was rather surprised to see some of the topics covered - I did not encounter these until A level. BTW, excellent presentation.

    Brilliant videos with which I was able to prepare specifically for GCSE. I also recommended it to my groupmates. I am very grateful for it.
