<p>So last year(10th grade) I moved to a new school. I had an A+ in Bio in my previous school. At my new school, the teacher was extremely unorganized and lost everything. When people told him they had turned in assignments he gave them full credit for it.</p>
<p>However, he didn't grade my assignments until the school year ended so I didn't find out he had marked 2 assignments missing until I received my report card. My grade was a C so I e-mailed him and he said he'd change it but he hasn't so now I'm stuck with a B- :/. Should I tell him about it or is it too late?</p>
