sitting in front of my lap

Hiya roger, I am a bit lost here do you mean you can´t keep the Laptop on your lap because you can´t or have´nt got any kind of stable surface to put it on or do you mean that it´s uncomfortable for you to sit there with the Laptop because you have already been there for hours on another Computer and you are too tired to concentrate? Or do you mean both things that you are tired and have no energy at the end of the Day to think of other ideas. I would use some sort of portable table you could even use a Wooden chair and put some Books underneath. Sounds also like you are too tired to put in many more hours than you have already. I imagine that you have a lot of exams and things to do as well. Well either way good luck in your projects sorry I can´t help much here.

I am also a computer science student. And I also worked as programmer. Maybe you have to design the system you are going to build first. Then you can start to code easily..

I usually keep on decreasing the power of the laptop screen!! It does happen to me too that my eyes get hurt and start straining too..but, I have found the decreasing power is the solution to me..well, it doesn't help that much but i feel much better as long as i'm capable to do my projects...
