The block schedule has 6 letters to represent different rotations.
A is blocks 1234, B is 5678, C is 4321, D is 8765, E is 2143, and F is 6587. Since we go to school 5 days a week and the rotation is 6 days, it was hard to remember what classes I had next.
Since looking at a piece of paper and using my mind power was inefficient, I made a program to email out the schedule to myself.
I thought, since I'm already making the program for myself, why not make it for the 400 students in my high school?
