Through my first 4 semesters I had a 3.0 GPA. During the last of these 4, I withdrew from 2 classes and received a D- in another. Over my final 5 semesters, I earned a 4.0. Needless to say I got my act together. Do you think I need to explain this shift in an addenda (especially the semester with two withdrawals and a D-)? I was in a rough relationship, and wasn't focused on school.
