Im stressing about my grades help me ?

Ok so all my grades are good except for one %26amp; I was old even after the Quarter is over you can still change it ( like submit a grade change ) but the E will still be on my report card . Reason why I have that is because I switched classes %26amp; then after that I never knew i had to make up wrok from the current teacher so I have a lot of missing grades . But the thing with this is im not the kind of student to get a E. %26amp; my birthday is around the corner %26amp; we get our report cards in like a week or so %26amp; my mom .. what do i tell her ? Or how do I tell her this ? Help me !!!Im stressing about my grades help me ?
tell ur mom about how u switched classes and how you have alot of missing work i think she will understand and maybe you can convince her to call that teacher and see if you can still make it up ask your mom to help you or ask someone in your class that has already done it to help you

hope this helps u
