This Progress Report is 10 multiple choice questions. Choose the best answer for each. You may use paper and pencil to organize your thoughts.   Do not use a calculator. Do not refer to your text, notes, etc.

After answering the Progress Report questions, you may either "erase" them by clicking on RESET, or check yourself by clicking on SUBMIT. Both the RESET and SUBMIT buttons are displayed after the last question. A Form Confirmation appears after clicking SUBMIT, and it lists each question as correct or incorrect. (You may return to the Progress Report as many times as you like.)  If you have chosen the Online Portfolio (CHE 103 students only), print the Form Confirmation ( or paste it into an email message) and send it to your instructor.
