Exam Review – Summer School 2013

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 course. Any assigned work is fair game for the exam.

Good luck and don’t be afraid to ask for extra help!!
