If you get all four answers incorrect, I would be tempted to conclude that some review on the material would be advantageous for you.

Tests and exercises are to give you an idea of what you have learned. There is no point doing exercises if you have not reviewed your work.

If you do not have a textbook, nor class notes, and have difficulty in finding reading material, please post. I will be glad to select some reading for you.
