working day

It is a working day today but it is not busy now.
So I can review my notes and searching the web by my own decision.
That is great!

However, it is hard to review these notes as I feel sleepy all the time.
Due to my working hour is all around the clock and without enough rest.
I feel tired.

Neverthless, the program of my FYP is not finished and it is still at the concept design.
It is getting worry and in hurry now.
What can I do now?
Programming?? But I have exams and I feel sick of it.
review all the time?? Surly I will to try my best in the exams.
On the other hand, the program will be late.

It is difficult for me to make this decision.
