I'm probably going to apply to Mathematics, or maybe Mathematics and Physics, in Cambridge this October. I'm not asking for your opinions on Cambridge or the course or anything, I just have to ask this. I am an Irish Secondary school student, and I am worried about the STEP exam required to gain entry to this course. I believe I have the potential to do well in the exam, but I am more fundamentally worried that the Irish syllabus I am following will not supply me with enough mathematics to complete the exam to my full potential. Anyway, I was wondering what else I should do to be adequately prepared for the exam, what books, courses, whatever, would be helpful to me for this.. Thanks in advance.
