First time solving a GCSE maths paper!

This is my first time trying all the questions from a GCSE maths Paper 1H on the spot. GCSE (General Certificate of Secondary Education ) is an exam for high school students in the UK. I mostly teach algebra and calculus at a community college here in the US and It will be interesting to see how the standardized tests are from different countries. This math test includes solving inequality, quadratic equations, rational equations, geometry, probability, and stats problems. If I make any mistakes in this video, please let me know and I will make correction videos! Enjoy
