Sleepy Studying

I was studying so hard and long for my final test today till I got so sleepy...
See below:

Not that I'm complaining about this module. The projects are fun & there're some interesting topics too. I just studied till too late.

Did you see it? Was so drowsy that I wrote music instead of meanings =/ And music is totally irrelevant haha...

This was written in lecture. I must say that the lecturer is pretty... hmm you know :)
Note the light squiggly lines below British & American. Those were supposed to be some words. What I do not know :D

But the test was done well today and itz the final test for this module! Meaning no exam! Whee~ 1 down! ^^
