  • Exam 1 is next Thursday, 9/25!!!
    • To start preparing for the exam, you should probably set aside two hours to complete the questions in the ``Chapter 1 Checkup'' section of the book. Pretend like you are taking the exam---put yourself in a quiet test-like environment and do not use your book, homeworks, notes, or even a calculator to help you complete the problems. Write out complete solutions as if I were going to grade them. Once you have completed all the questions and are satisfied with your answers, then AND ONLY THEN, compare your solutions to the answers in the back of the book. If you are unable to do one or more of the problems, DO NOT LOOK AT THE ANSWERS. Seek help from (a) the math help room, (b) your classmates, or (c) see me in office hours! If you look at the answers prematurely, you will be cheating yourself out of a learning opportunity and will not be able to do similar problems on the exam, when it really counts.
