The theme

Instead of naming our programme as Orientation, we named it MEDT109 Bootcamp. Bootcamp is a metaphor of orientation, an idea of 'training' the incoming students, or freshies to adapt to their new surroundings, Medical (or Dental) school life.

The event goes with "Ground Zero: Can you survive?"

"Ground Zero", means Where an activity begins or Where it all started or simply the starting point, and this refers to IMU, where the life of the students begin. This is not to be confused to the 911.

For "Can you survive?" it is a question to ask whether the students can survive medical school or not.

The theme name was suggested to meet the purpose of the orientation, to ensure that the new students can adapt well to their new school.
