The best way to get maths, is to practice it . Pretty Simple. I will start by going through the topic, going through examples of what is being discussed, then make you do questions that will range from easy to hard. I can also help with any homework you have or anything you are stuck with. If you are an A-level student, then I can still help you with AS-level maths, further maths or physics. As that's what I do. My experience till now as been decent, I sat my maths GCSE in year 10, and further maths in year 11. In year 12, now that we have finished covering the content, my further maths and physics push doing past paper questions. Sometimes the problem is not the content but the lack of practice and the lack of understanding the questions. Questions can't be the same in wording, but the same in answer. The more you practice, the more it'll stick.
