Katie,

When you get near the end of completing a degree, most people do have a hard time paying attention in class, and are burned out from all the previous hard mental work it takes to be in college.

I teach college economics, and when we go through certain parts of the curriculum, I tell my students they may not feel like they will understand this part as I am lecturing. Sometimes it takes sitting down and really staring at the material in the quiet of your room.

I hope this helps.
