If your a student, the college should have a computer you can use, in the dorm, a lab, the library. Since you can get online to post this I assume your also using something powerful enough to write this code yourself.

I'm using my Samsung Galaxy Note 4 to post this. I live in my own house and the nearest place to get a pc is 10km from here :/
