Dear Editor,

This is a sad situation to the affected students who have tried their best but come short. But for others who have not making any effort at all, may be this is a wake-up call and a wasted opportunity. And the reality now is the opportunity is now gone.

The second thing I wanted to say is to support George Kalo's call for the responsible authorities to research, find out the root cause and rectify it to avoid future embarrassment.
