A level maths

Hello, I got A* in Mathematics and I think I may be able to suggest a few points based on how I achieved it.
First, read through the textbook, make sure you understand every single concept, then do the practice questions at the end of each chapter.
Secondly, do past paper. It helps to find problems that haven't come across on the textbook but somehow being tested in the previous exams.
Finally, when doing the exams, make sure you allocate your time wisely, don't lose marks due to bad time management.

Good luck
