All HW assignments will be dues on the final exam day, June 6, 2016. - The lowest midterm score will be dropped. Only three exams will be counted. - You must take the final exam to get Credit for this class. Failure to take the final exam will result on a course grade of "F". - All tests will be closed book, but you will be allowed to have one 8.5 x 11 “formula” sheet containing only formulas, unless otherwise specified, and a calculator. A violation of this rule will carry a consequence of relinquishing your “formula” sheet. All tests will be taken in-class and limited to one hour. Test questions will be mainly problem solving style problems. You will be required to show all work to receive full credit. </p><p>MAKEUP: No make-up tests will be given. </p><p>CHEATING: If you cheat on an exam, you will receive a zero score for the exam and are subject to further disciplinary actions through the College.</p><p>CLASSROOM BEHAVIOR: All electronic devices such as cell phones, pagers, etc.… must be turned off.

WORK EVERY DAY. Set aside at least two hours EVERY DAY to work in mathematics. Do not wait until the weekend. 2. READ THE BOOK AND TRY TO UNDERSTAND EVERYTHING IN IT. Before working any homework problems, quickly read the relevant sections in the book to get the main ideas. Then read them again, carefully. When you come to an example, close the book and try to solve it yourself. When you get stuck open the book and find out what the author does. This way you will learn what the difficulties are and how to get around them. Only after you think you understand the text should you work the homework problems. That way you will get the most out of them. 3. WORK MORE PROBLEMS. Work the hard ones, the ones you don't know how to do (at first). Work problems that were not assigned in the homework. Answers to many problems are in the back of the book. If you're unsure about a problem find one like it which has an answer in the back, and work that one first. 4. ASK QUESTIONS. Come to office hours or use the phone. If you don't want to (or can't) ask me, ask somebody else -- another faculty member or another student (get their phone number and you can help each other on your homework). Don't be afraid to "look stupid" by asking a "dumb question". HOW TO FAIL 1. Don't study until the weekend. That way you will always be behind. Because you didn't do Tuesday's homework before Thursday you won't understand the Thursday's lecture. By the time the weekend rolls around you will have forgotten Tuesday's lecture, too. You'll be facing eight or ten hours of homework in a subject you haven't looked at in a week, and you'll have to learn it all on your own. Good luck. 2. Don't read the book. When you come to a homework problem you can't solve search the text for a similar example and try to copy it. Otherwise, ignore the text. That way you'll never be able to solve a problem unless you have something to copy or unless it is exactly like one you've seen before. You'll never really understand what's going on. 3. Do only the easy problems. Better yet, don't do any! 4. Don't ask questions. Be afraid that you'll look stupid if you do.</p><p>4</p>
