I used to do that in all the classes that required attendance. Then I would stop at 7-11 and fill up the largest Big GUZZLE with two forties of Bud Light. Sit in the back of class, ripped and happy as hell. I had previously secured the answers to all of the tests in my classes and told the teachers I had adhd and couldnt concentrate when taking tests around other people.
Then i would go to a special, secluded room, with my Big Gzzle and copy the shit down.
I graduated at he top of my class in college and was ripped during virtually every class.
