Oh hun, reading this killed me just a little bit more. Wonderfully penend though I think it could be reformatted. Nicely written

So true.
Parents are just bothered about grades and nothing else.( well I guess you are addressing your parents here).

I think you should add 'they' in the last line of your poem.
"I'm dying
and they just don't care."

I love how you describe grades as "a letter on a piece of paper."

Well done.Being a student my self, I can relate so much to you.

Keep writing.
