Instructions for Using the Online Extra Credit System

For one point of extra credit, complete at least ten exercises from any of the problems listed and get a score of 90% or higher.

• Example: getting 9 out of 10 exercises correct would count for a point of extra credit.
• Example: getting 8 out of 8 exercises correct would not count for a point of extra credit (you have not completed at least 10 exercises.)
• Example: getting 89 out of 100 exercises correct would not count for a point of extra credit (you do not have 90% correct.)

When ready, press the "Submit Your Score" button at the bottom. You will be asked to fill in your name on the next screen, and pressing "Submit!" will record your point in a database.

If you need to enter a number answer in scientific notation, use the "E" format. For example, the answer 1.03 x 10^-3 would be entered as 1.03E-3.

There may be a limit as to how many online extra credit problems you can complete per term; see the syllabus for more information.

Every attempt has been made to make these JavaScript problem sets as browser friendly as possible, but if you find an error, please report the error as soon as possible. Every effort will be made to correct the problem promptly. I highly recommend using the most recent version of Safari, Firefox or Chrome on these problems. Do not use Internet Explorer!!!
