This is HW #12 due Wednesday, Sept 29 (Test Day)
Listed below are six major concepts. To receive full credit, you must pick at least 4 of them, and complete one problem from each concept that you choose (the practice problems do NOT count – those are for you to refer to in the BOB for reference). If you feel that you need the review, then you should do problems from 5 (or even all 6) of the listed concepts!
Work must be in complete sentences and in context. Do what you need to prepare for your test!!!
Again: “Practice” problems are optional (no credit for those)!!! Do at least 4 of the 6 for full credit.
