Maths, Physics and Computing tutor teaching at GSCE level and below

I am studying for a degree in Robotics at the University of Sheffield, and I achieved an A* in both Mathematics and Further Mathematics at A-Level, as well as an A in Physics and Computer Science, so I am well equipped to tutor at a GSCE level (in which I got 9's in all of the subjects mentioned). I also have experience working with under 18's from four years of volunteering at a local youth group.
