Math Diagnostic Quiz
Try it yourself - we'll go over this in review and SI sessions! Answers to the quiz.

Bonus Opportunity Problems (BOPs)
Note: I'm primarily assigning odd problems.
The answers are in the back of the textbook and worked out in the solution manual (found in OWL on the left hand side) if you are having problems.
Our SI leader works out BOP problems during SI sessions.
The solution manual is now included with OWL. You can also go on line and buy yourself a copy. They are meant to be a little more challenging than OWL and a bit closer to exam problems.

You MUST include all your work for calculation problems, or I'll have to assume you just copied the answers.
If you put just the answer down for a problem that you couldn't do in your head, you will get a 1 for the entire assignment.
