While preparing for an exam, we all compete with ourselves and our peer group and try and exceed our own expectations. For that to happen, we need to familiarize ourselves with the best and the latest content available in the market. Also we need to know and be hands on with, on how the exam paper will turn out to avoid any surprises. The best way is to this is to go through the previous year question papers. When the exam is big and popular as the International Maths Olympiad (IMO), it becomes even more important. Maths is a subject which can never be mastered and there are always lots of questions to be practiced so why not go through the ones which have been asked in the past. The previous year papers give you get a hands-on experience of how the pattern of the paper actually is. You should also keep in mind that this is an international exam so you are competing with other students all across the globe. Here, at SOF Olympiad Trainer we provide IMO Previous Year Papers of the last five years in order to help you in preparation. These papers are given along with the answers and solutions.
