Response: The main purpose of the practice test for Test #1 was to acquaint you with the timed test environment with limited submissions. For Test #2 I've given you a much larger batch of problems to practice on, and you can practice on them for as long as you like. So the purpose is somewhat different. You already are acquainted with the test environment, so the practice problem set is more for the purpose of preparing you for the test than for mimicking the test environment.
Spring break is next week, and there are no homework assignments due during the week. The practice problems are mostly recycled homework questions (with different numerical values), so they give you an excellent review opportunity if you want to keep from getting too rusty next week.
