This is a quiz database made by a student. While the class notes from the University of Calgary have been used as reference materials, this website has no affiliation to the University or the instructors involved. Please do not associate the information on this site with the University of Calgary.
If you get an answer wrong, please keep selecting other options to reveal the correct answer and explanation (if it is available). You should be able to score at least 95% (if not, go back and study your notes) because the scoring algorithm is: # right answers – # of attempts / # of questions answered * 100. So even in the middle of the quiz, you will be able to grade yourself on how well you did up that point without completing the entire quiz.
