["I just had a huge test that I was supposed to pass. I bragged to everyone that I would, but I don't think I did.", "Oh no what happened? Why don't you think you did well?", "I spent so much time talking about studying and didn't really study that well. I think I'm gonna have to inquire about the grade, it's eating me up inside!"]
I hope its better than you expect!
I was supposed to study for a big test in college, and I made a big deal about passing it. I didn't study as hard as I should've and failed.
