Weird

I'm looking over my college transcript right now (As I'll be registering for classes tomorrow) and I've noticed a little irregularity. I seem to only receive Academic Honors (GPA above 3.5) during the spring semesters. Every spring semester, academic honors, but every fall semester I seem to be just below the line. I wonder what that means. Do I simply take easier courses in the spring? Or, does it actually take me a whole semester to get back into school after 3 months off? Oddly enough I feel this year will be much of the same ... Shall history repeat?
