What do I say in an email to my teacher concerning the grades he has posted for me?

my school has an online thing where you can go check your grades, and being that mid terms are next week I went to check mine. my AP teacher has a lot of blanks for grades on my list for things I am sure I have handed in.

This is not something he would want to talk about durring class, and I don’t have time to see him after school. So I was going to send him an email tonight concerning it.

What do I say besides: “I was on PowerSchool tonight and I noticed a lot of empty spots for grades, and I am sure I have handed these things in. I don’t want these to affect my final grade this semester. ”

THANKS(:
