The Sir Isaac Newton (SIN) exam is a test of high school physics and is offered by the Department of Physics & Astronomy at the University of Waterloo to encourage the teaching of physics. The exam, although challenging, is meant to be refreshing and fun. Political and other topical humour have marked SIN exams for years. Students participate from across Canada, the USA and abroad.

Students should approach their physics teacher or guidance counsellor who will have access to all the details (or they can get the details by visiting this web site).
