Thanks a lot.
I got 75/75 in a past paper.

I just finished GCSE's and I plan to do Math and Further Math for A-Level. Giving myself a head start, I decided to watch your videos and do notes on all of them! Thank you so so much! Most of it is GCSE work on these videos haha!

At 2:10, could I say that the line is a tangent to the circle because the discriminant is equal to zero, as an alternate answer?

Can you help me out in a question?
Determine the equation of the tangent to the circle at the point F(-2, 5)

Hi Sir, I am struggling to figure out how you got the gradient of the tangent at 3:09.

For question 2 why didn't you use the negative reciprocal of -15, when finding the Normal?

have you done videos on aqa d2, had a look and didn't see any and was just making sure, btw your videos have been a huge help to me over my exams the past couple of weeks

Hi sir, what did you think of the C4 paper?

I thought it was difficult and more difficult than last years paper.

Please let me know, thank you.
