Basically , im top set maths and everyone in my class got very low grades with a few exceptions , basically most of them got less than 20 out of 80 and I only got 16 and my mom isnt very proud. How can I revise for maths lets say i am good at algebra but terrible at other aspects of maths such as histograms and probability especially angles and shapes. Where do I start, should I start revising on the hard stuff or start from the beginning like number and ratios since I am very bad at them and never got a chance to learn them properly,how many hours should I study for maths, any good books for gcse since I find textbooks easy to understand when it comes to maths. Lol I know lots of question but I love maths somehow and wanna do it in A level but im clueless
