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.
