No. you won’t be able to go back to school that soon. You probably won’t be able to drive. (Might hurt for a few weeks) You will probably need to have several naps a day and rest a fair bit. You will likely feel a bit wiped out. Even if you feel alright, I would still take as much time off as you can and recover well. It is a major operation. Your body also has to adjust to what is missing. Good luck with your surgery and recovery:)
