I'm in the same situation.....go to class @4 and my lecture are only 1hr & 50 min, then i go stragith to work, @ my hospital I do 12 hr shifts...... then whe I get home in the morning I go straight to bed, and then back to class or clinical depending on the day of the week. I just completed my 3rd semester, and I have 1 more left, it is stressfull, but I have survived this far..
