	Message Board Biology - Mr. Galian

THIS WEEK (12): March 22, 2010 Monday

Welcome Back to SCHOOL!

Notes: Hope you guys and gals had a wonderful spring break. You are on your last stretch for your freshman year. Now is the time to motivate yourself not only to get through it but actually get an A in my class - is it possible? Yes - you have to work for it!
