During my undergrad studies, my first two years went fine but in third did not go well as compared to the first two years. Consequently, there was a drop in the GPA. But there was one good project at that time and I and my roommate did some independent research work during this time which we got published in beginning of our final year.
The main reason for the drop in GPA was due to trouble in catching up with the subjects. I just could not handle my studies at that moment.
Though it was the third year when I realised which field of computer science I wanted to specialize in, so since then all my projects, independent research work and even some research work under my professor has been related to that domain.
I must also add that my GPA increased every semester since the drop.
I wanted some suggestions on how to present this in a positive way in an SOP?
