Nope. Problems are more things like: I can't grow hair, I grow too much hair, I never lived in the same house for more than a year, I've never been allowed to leave my parent's basement, my dog ran off with my girlfriend and they took my truck, I killed a man in reno just to watch him die and now I'm stuck in Folsom prison (despite the warnings of my mother about playing with guns), etc. I had some bad grades one time and then got over it isn't really what they are looking for. If you need to talk about a lapse in grades or your struggle to improve them do that in a different essay. For this one try to find some other problem you have had to face. (doesn't have to be as dramatic as the examples posted above)
