I know what you mean. I always had trouble staying focused in math classes. Pretty much just 'cause I was never too good at math (takes me a while to soak information in, for example I wasn't really profficient in Algebra 2 until a year after I took the class, then it finally connected while I was in my trig class) so I just stared off into space.
