Hi Wei Qi,
As I understand from my team manager for the table tennis, the games on the 12th May 2013 is not a suitable dates for some of the players as it is an exam period and also the National Junior Team selection.
We have some players whom will be affected by that day and will not be able to make it on 12th. Can you take a look at the other dates, hopefully after 18th May.
The match day on 19th May is fine and any dates after that will not be of any issue.
Sincerely,
Ken Ong
Chairman
