Butterflies in my stomach

I'm at the Management & Marketing MGT346 lesson, they are presenting but i'm not. I came to get presentation tactics from others my turn is coming this Friday. I have stomach cramps already,

This track just drives me crazy....Its a sound track of Step Up 3

This is a nice song!! I usually play it when I'm feeling down....

EXAM

Exams are coming very soon, I have 4 hard exams this semester. I can't seem to focus, my study tactics are failing this time around. I don't what is happening to me. I have managed to do 1topic on Performance Management ACC307, for the whole of yesterday, if I move at this pace I don't think I'll be able to finish all the topics for the 4subjects. Eish! I also have Principles of Corporate Finance FIN322, this one I don't want to retake it but if I don't study I wont get anything for the exam, its really tough plus the lecturer is not willing to explain to us if we don't something clearly, he gets annoyed at the questions being asked. His teaching style I don't understand but I'll be seeing him again next semester for Corporate Finance II this is sad.

I think there is something wrong with me, my concentration span is 20minutes from there I start doodling, my mind just go somewhere else or I feel sleepy. This is unlike me.

What do I do??Ohh Lord have mercy on me....
