I did something similar when I was in college to fix my bad grades - I didn't have a laptop or a computer at home, and didn't own a smartphone. I did all my school related work at labs in college, and this made me much more productive at home - instead of mindlessly surfing the internet, I actually did the school work. As a result, my grades shot up to summa cum laude levels and there is a distinct step function between my freshman/sophomore year grades and the junior/senior year grades. Unfortunately, living with a girlfriend who adores Netflix, I am back into my procrastinating self when I am at home.
