Hi, I always found Maths Genie really useful for studying maths. They go through whole A-level papers with examples and step-by-step examples. I love that sort of stuff. Sorry if it's not for you. Keep up that determination, studying independently for Further Maths is a GREAT achievement! You can do it!
Trueee i literally used mathsgenie and watched the gcse maths tutor on yt and got a 9 so they're both amazing resources to use in all honesty but for A level fm the gcse maths tutor doesn't go in that much detail. But it's okay i'm planning on buying a lof of fm practice books and hopefully i'll be able to get through it.
