Finals Week-leaving early...

i got up this morning and found a email from my boss telling me what time i work on finals week. i was soooo happy. i first looked at it and found out that i work on wed. so then i could have skipped my last final that i have on friday because i dont have anything past wed til friday. i was so happy. then i look again later in the day, comes to find out that i have to work on thursday. :( ok i guess i could go home on thursday around noon. then i get an email from my professor saying that we have to show up for the final on the final day and sign a piece of paper saying that we are leaving. i really had my hopes up for leaving early! urg!!! nothing ever goes my way!!! :(
