Should I say yes?

Okay, so in one of my previous questions I talked about my math troubles. Well, my dad is a deacon and one of the sextons at my church ( the one I mentioned in my earlier questions) is a genius at math and he lives in my neighborhood. My dad suggested that he ask him to help tutor me and that he would pay him, etc. Should I say yes to my dad’s idea because I really like the kid and it would be a good way to get to know him better.

However, I’m conflicted because he would eventually see how horrible I am at math and it would be kind of embarrassing. I just feel like it could end badly. What do you think I should do?
