How to ethically/morally "bump" up a grade?

Okay, this question sounds really weird so I ll just explain.

Before the finals, I had a 91.43 in Algebra II, after the finals I now have an 89.43, but we ve had this week basically doing nothing. I asked her if there was something I could do that get my grade up to a 90, but I already did my homework and extra credit and she said she really does not know any other option. She would be willing to do something for the entire class that could increase their grades, but she does not know what activity that would be fair. I only have 2 more days before the semester ends. What are some ideas?

I’m ok with a B, but if I can get an A by giving my teacher a good suggestion, id rather do that.

Please just give me suggestions

Ask if your teacher would be okay with dropping your lowest daily grade (or a grade that is not as vital as a test but dropping it would enable you to get a 90).

Do something good. E.g. learn some abstract algebra and write up a detailed exposition on it and its beauty. Or some minor research, or something that shows you deserve a better grade.
