The time stamps are my tme FF. I posted them to show activity was spreadout during the day not where you were at any particular moment.
Oh.... I see, well, I generally have a few seconds (or minutes, depending on which class it is) at the end/beginning of each class. Like today, I had about 2 minutes per class, except english. So I do technically have "time" on AC, but not enough to read 7 pages of information. So I would never bother to try except when I have a LOT of time to do so, like the 20min homeroom class or 45min Study Skills (basically a study hall).
