Our first unit test is in September, and you should expect at least two quizzes before then. What are you doing NOW to be prepared? Use these resources wisely: try the homework independently and pay attention to which problems you needed to consult your notes or the solutions to finish, discuss some of the problems with your classmates or a friend or family member, redo the more challenging problems until you can finish them without referring to outside sources, ask yourself how questions might be phrased differently or how a problem might be twisted to look at a concept from a different perspective. Ultimately, you will be tested on these concepts, and these homework problems are designed to help you develop a strong understanding of these concepts.
Keep in mind that these resources might still be helpful even after taking the test.
