Exactly same what i have done and remember of it ...The speaker mentioned that we are the starting point, and if you take the corridor to the left, you will see the first place. That was moving from the central point to the left, you get E. Point A was beside the seminar room.
The speaker then said that we return to the starting point and that the third point is on the left. That means the place immediately to the left of the starting point is the third place. Then C is at the end vertically to the starting place. Dis towards the exit.
