Here is the practice test prac_test_1 to help you get familiar with the format of the test on Wednesday.
The practice test is just to help you understand the length, rough content of the test. The actual test on Wednesday is NOT going to be the same test with different numbers.
Key will not be posted, these are all problems from your homework/lecture/self-diagnose quiz. Do feel free to check your work with me, either in office hours or email me a photo of your work.
