Replying to NS, i call upon thee for help!

check it, here's my situation

i'm in the process of signing up for courses for the fall term at college, and i'm torn between two of my options.

so ,

either i....

a) sign up for two labs, tuesday and thursday from 2:30-5:30 (both of which are my only classes all day, so mornings off = yayyyy!)

or ,

b) sign up for both labs on thursday, one from 9:30-12:30 then the other from 2:30-5:30 and have tuesday off completely.

so basically what i'm asking is should i split up the 6 hours of class to two days, in effect freeing up my tuesday and thursday mornings, or should i put all 6 hours of class on thursday, giving me tuesday off

thanks,
justin
