Online Maths and GCSE Computer Science tutoring with an experienced Queen Mary University student

I am a Computer Science student at Queen Mary University of London and I can teach Maths from SATS to A-Levels, and the way I teach it is that I provide the basic concept of the topic and solve example problems on topics you struggle with using my iPad while explaining them to you. That way, I can let you do other questions you can attempt, and whichever you get wrong, we can go through together. I can also teach GCSE Computer Science, mainly the programming side (Python), but I can also teach the theory too. With Computer Science, I would like to know the topic you want to cover in advance, so that I can prepare the teaching material.
