there is a great difference between completion and accuracy. you could complete a task or an assignment within a matter of seconds, but the quality or clarity of the result of this task could greatly affect your work ethic and responsibility. i think it is so fucked up when teachers only collect homework for completion rather than accuracy. sure, it is easy to be lazy or take advantage of that by answering with whatever the fuck you want and still get an a on that assignment.
then you have the teachers who properly grade on accuracy and you can visibly see the difference. you're learning more, you're studying more, you're prepping for exams more, and you find yourself cramming less at the end of the semester. again, i can understand how it sucks to sit down and get to work instead of doing what you want, but i am telling you from experience, if you take at least a half an hour per day to review material or actually take your time on homework, you will achieve and excel better in the long run.
