CONFUSE-D

I'm confused with the weeks, DAMN! In highschool, we dont count by weeks, we count by terms so yea this week thing is so like NEW to me. I have to do a presentation on the 8th week, i'm not so sure what date is it but i think its in April. SEE? CONFUSED! My Media teacher himself is confused. Now can you think of ANY reason at all why i shouldn't BE confused? =)
