I'm currently doing 3 a levels consisting of Further maths and Maths Edexcel and AQA Physics. I revise on average 6 hours a day during weekdays and 12 hours during weekends. Would this be a good practice for university as I am planning to do a degree in mathematics in September? What I mean by this is that how much work do you need to do to secure a good grade at the end of each year at university. Second question: What books/websites would you recommend for self-studying before a mathematics degree as I'm going to be a no-life neek over this summer.
