Answer
In a round about all traffic is going in the same direction.  I suspect that the instructor wants you to enter the round about and take the third road out of the round about.   I.E. if you enter heading northbound into the round about, continue until you can exit going westbound (that is the exit on the left from your original direction of travel).
