SBI 3U Ms. Girvan Exam Review 2012-13 Your exam will be composed of types of questions that fit under the four assessment and evaluation categories: knowledge/understanding, communication, inquiry, and making connections. Practice each kind of question in your review. The exam covers material from the entire year. Any assigned work is fair game for the exam. Good luck and don’t be afraid to ask for extra help!!
