This page is devoted to monthly online extra credit questions and the notification of extra credit opportunities. The answers to the monthly extra credit questions must be e-mailed to me.  You will find a link to my e-mail address on the top of the page. You have one opportunity to correctly answer each monthly extra credit question. An answer must be received by midnight on the last day of each month to be eligible for the extra credit. Please be sure to take advantage of this opportunity.  Good luck! March Thank you to those of you who attempted last month's extra credit.  The correct answer was 72 cents.  Here is March's Extra Credit: At what wavelength does the FM radio station 106.9 broadcast at?  Remember to show work and include correct units to receive credit.  Good luck!  Mr. C
