^this. If you’re finding it that difficult, don’t do it and just drop it. You not only need to enjoy the subjects you’re doing to a certain extent, for your mental health, but you alos need to be able to do well in these subjects. If you’re constantly failing exams even with hours of practice, then maybe maths just isn’t for you. As the above person said, do you NEED a-level maths to do computer science? Or do you have a handful of unis you could apply to for computer science that don’t require a-level maths? Because if you have options where you can still do computer science at uni but don’t need a-level maths, then drop maths and pick up another subject.
