How Do You Tell A Teacher That You're Having Family Problems

I have 74.03% in Chemistry and I really need at least a B. Throughout the year I’ve been stressed with family issues amd I honestly think that’s what is holding me back so much. School ends on May 26th. My teacher also doesn’t offer much extra credit and if she does, it’s only one problem. I’m not going to ask her to just give me a B. How should I approach her and tell her what’s going on and ask for extra credit?
Thanks!

No. You can ask for extra credit assignments but they aren’t going to give you a grade you didn’t earn.

They could, but if they barely even do extra credit, it’s unlikely that they will, IMO.

You might try talking to your GC about it and they might be able to help you work with the teacher if there are assignments you missed or something you can make up.
