You cannot just say ';hey teach, change my grade!';



If you feel that your assignments deserved a better grade, get another teacher of the same subject to review your major assignments and get them to grade them (this may not be possible however). Otherwise, ask your teacher to review those major assignments with you to explain to you why you got the low marks.

Otherwise, how about working hard in class? Not that hard.
