I’m currently doing methods right now, so I might not be the best person to give advice. I feel like for maths, the best way to really improve is to do heaps of different types of questions. I recommend looking through the examples in the textbook before attempting a question and try to understand the method. Then, you should attempt it yourself and if you get it wrong, look at the worked solutions and try to understand why you got it wrong and repeat the question until you get it correct. Like the person above, I feel like if you’re struggling, you should definitely ask your teacher. For algebra, practice makes perfect and in my opinion there’s no shortcut to refining these skills. For graphing, you’ll need to kind of memorise the general shapes of every graph and apply them to the questions. It helps to understand why the graphs have their certain shapes. In my opinion, maths is one of those subjects where to improve, exposing yourself to heaps of relevant questions and understanding them generally works.
