Pertaining to college students and organizers alike

My semester just began, and I like having a planner to write down all my assignments ahead of time. Having got my nexus 4(first android device) I've been scoping through the pay store to find a nice full featured planner to aid throughout the semester. Unfortunately I haven't found one that is truly a full fledged smart phone planner. I have learned through android though that a lot of the best apps don't show up through a simple search and are usually hidden in the play store

My question to the "android army", mainly college students; what planner app do you use that had worked best for you?

Mainly looking for the ability to separate exams, homework, professor information and things like that.

Myhomework has gotten me by so far but I'm sure there is something better with a nicer UI and organization.
