NEED to concentrate
 

I have a few more assignments left to do, and two weeks of classes (I can turn stuff in late if needed), and I really want to get this done... once my work is complete I can coast for several months... Any ideas on how to concentrate with a headache and fuzziness? If I manage to do well again, I could get a significant scholarship for next term which would REALLY help...

Any ideas, truly appreciated.

You could try some Extra Strength Excederin for the headache and take breaks often. Go outside for a little walk. Take small naps, rests in between working.
The Excederin has a lot of caffeine in it so it helps to clear the fog and sharpen concentration for a few hours. Don't push yourself too hard or it will set you back more. Eat some oatmeal and fruit. Take good care of yourself. Good luck. That is great that you could get a scholarship! I am proud. My daughter is also a candidate for scholarships.
