Sorry if this question has been asked a lot before, but... What books would be particularly useful to read before starting university? What books explain tricky undergraduate-level topics really well? My course will hopefully be Mathematical Physics, so any recommendations of maths books (pure or applied) for a beginning student would be particularly useful, as I tend to find maths harder than physics. I tried looking on the university's website, but they don't seem to have any recommended reading lists. Thank you for any advice.
