In this type of station, candidates are allowed to rest and sometimes offered water or can talk to a current student.
Students have said that the break station throws them off during the actual MMI. Do not take the time to rehash all of the previous stations, or work yourself up over what questions could be next. Take a break from talking if that is what you need and try to breathe and relax. If there is a current student at the rest station to speak to, be polite and interact with them. Use the conversation to help calm your nerves/get your mind off of waiting.
