MINDFUL MATHS - My aim is to share the videos I make for my students with the world to help with understanding and revision. The videos have been recorded in lessons and cover any misconceptions that come up live when teaching.
Edexcel International A-level Mathematics following the Pearson's student book.
Remember these lessons are to support and I do not recommend just using these, you also need to practice different styles of questions and complete past papers.
Mathematics is better learned in groups so you can improve your problem solving and reasoning skills. You got this!

MISTAKES - I will put any corrections here if there are any – remember mistakes happen sometimes and if you have nothing nice to say then don’t comment, we are only human. 😊

Loved the way you explained the CAST diagram. Also, great Video and helped me alot thnks❤❤

[Brisa-setu]

Ur voice is so charming that I literally dive into it 😂❤❤❤

Woah I missed this chapter in my school and you helped a lot! Did you create these powerpoints? Because my teacher uses the same powerpoints in class!

14:40 isn't tan square root of 3/3

[abdalrahman]

01:05:40 shouldn't the other line be in the 270/360 interval? since its for cosine, or do we just reflect the cosine vertically and sin horizantly and tan against y=-x

[kgaming]

in 37:06 i made 1/cos^2 -1 = 1/cos^2-cos^2/cos^2 is that correct

[afifaalam]

helloo i have a question in 1:27:28 why wont the line reflect

[marwinsteiner]

Forgive me, but what's silly cow?
