One should know and understand knowledge learning takes time. No one could absorb information, digest it and apply what they’ve learnt within a few short days. The flight time and acclimatization alone could take more toll on these young students, let alone the learning aspects. By the time that student has settled down, it is more or less time to leave. Hence, the net effect is like a rolling stone that gathers no moss!
