1 Math Final Examination STUDY GUIDE Fall 010 Name Score TOTAL Final Grade The Use of a calculator is permitted on this exam. Duration of the test is 13 minutes and will have less number of questions than this study guide. This study guide does not necessarily contain questions from every possible topic covered by the final exam. Any topic covered in the course may be represented in the final. It is recommended that students study all topics of the course. We also recommend studying chapter tests and chapter exercises. All questions are the property of Math Department at Kent - Trumbull. Final Exam composition is in TWO PARTS as follows. PART 01. Approximately 0-0% of the Final Exam is to come from First Book (1001 Book). Please study Math Test 01 (= Math 1001 Midterm) Study Guide and Math Test 0 (= Math 1001 Final) to prepare you for this part of the test. Both of these STUDY GUIDEs have been circulated before. Breakdown of the Final exam is Approximately 0-% from each study guide. PART 0. Approximately 0-60% of the Final Exam is to come from Second Book (100 Book). Please study Math Test 03 (= Math 100 Midterm) Study Guide circulated before and the attached questions that cover the latter part of the book (material covered after the Test 03) to prepare you for this part of the test. Breakdown of the Final exam is Approximately 0-% from each study guide. MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.
