Note to student:
I am a Ph.D. candidate at the University of Toronto Institute for AerospaceStudies and a long-time math and science tutor for high school and univer-sity students. These questions are designed to help you practice for yourhigh school math, physics, and chemistry exams as well as your universitycalculus and linear algebra exams. I have designed most of these questionsand have based some on actual high school and university exam questions.If you are proficient at completing these questions, then you should be ingood shape when facing most evaluations. If you have any suggestions foradditional questions or wish to report any corrections, please email me.
Good Luck!
