First year summer bonus? FT?

I'm a first year uni student working at a BB - I joined at the beginning of the week and got staffed on a live transaction with 2 VP's, MD, and a senior analyst that just got fired on Monday. Apparently, my work was "above-par" for someone of my age/credentials and they are going to give me a big bonus at the end of the summer. Has anyone faced a similar situation in the past?

My MD asked me to take a semester off school and help them with another big transaction they're going to be working on this winter. Should I consider?
