history: I am going to do better this semester. Last year was a travesty. I am going to do much better this semester than last. I'm glad you have a good plan for success this semester.  Did you pass last semester?
current: I did, but barely. I have a good plan. I got a good schedule and the classes I want so it should work out.
next: That is really good.  I've found that a good schedule is the backbone of a good year.  It sounds like you've got it figured out.
