At first, excuse me if the topic isn't at the good place in the forum, but I'm not vietnamese (i'm french), so I don't understand vietnamese, so, thanks to moderator to transfer my topic to the good place ^^
In fact, I would know if there is some summer math camp in Viet-Nam ( training for IMO) for forgeiners, more precisly in HCM, bevause I know people there who will able to lodge me (I went to HCM in summer 2006 :-P )
