Obviously the logistics of Day 1 as an MBA depend on the program you enroll in, but I'm sure at some point you will be sitting in a room designed for lecture and discussion. Your name plate sits prominently in front of you as you sweat being cold called. It's a beautiful thing!
Key tools for surviving:
A good laptop
Lightweight and fast to start up are key in my opinion
Access to your class WhatsApp, GroupMe or Slack
Need to stay in the loop quickly on changing assignments, class advice and of course the social scene
I don't think people talk about how important good footwear is in school- whether your trekking across campus or standing up at a networking event for hours on end- make sure your shoes are comfortable and suit your style.
