SNC1D Exam Review
Please keep in mind that this review is intended as a guide only. There is no replacement for your own determination of the topics and concepts that you feel are most important in the course. Please also consider that the exam is equally weighted amongst the four different units. There will also be multiple choice questions for the entire course
