Maybe ask him/her to go over the questions you are having problems until you understand and once you do keep practicing them so you don't forget by exam time, if you feel your going to fast then tell your maths tutor and he/she should slow down teaching or change to help you learn better. I really hate maths, when I was at school and college everything had to be explained a few times for me to understand it and I had to keep practicing to not forget. I'm so glad I am not studying maths at uni now and will never do so in the future but you must enjoy maths if you're studying it at a level. Just ask your tutor for more help or recap what you did last time everyone you see him/her, read over the methods of answering questions and keep practicing!
