I have finished all school-level math while I was in my country, but because of political and economic situations of my country I had to flee it with all my family and so I was out of school for so long as it was so upheaval, now I am starting GCSE this year just for the sake of doing them to have the “paper” qualification to apply for higher level, I think I will smash it to A* and I am using your videos to refresh my memory of math as it was my only and only favourite subject, maybe history was after math my little bit favourite.

Thank you.

Hi! You have an amazing accent. It sounds like a mix of Australian, British and Irish. Also, your way of explaining is amazing.
