So you're going to be exhausted and might have problems thinking straight? That's the most basic of problems in all forms of education.
Yeah, education, the curse of modern people ...
I'm really interested in what I'm doing, although I didn't get what I'm learning this Physics basic stuff for yet, but I'm sure I'll know in some time. And I even expected it to be that much work, but it's still a bit strange to face that amount of work after months of basically doing nothing.
