I think I've been caught cheating on my math culminating.

I really DID cheat on it, you can't blame me, I don't understand shit. My math teacher has emailed me with the subject "math culminating", I haven't opened it yet, but I know it isn't good. I do have an excuse, though it's pretty bad,

"I was on a call with my friends and they helped me through it."

I know this is my doing, and I know she can't really do anything except fail me, but I can not fail this course, my mark is already horrible and my culminating is worth 30%, so if I passed, my mark would be a 55 or something, which is low, but passing. Oh, I know the teacher is there to help with everything, but I don't understand math from a teacher's perspective. 

I don't know what the purpose of this post is supposed to be, I guess to hopefully find other fellas who got caught cheating? No idea.
