its a good suggestion that you hand in by hand there ... but since you said you have received the email from them .. can you give us the email address that they used to reply you ..so we can actually ask them whether they have received our applications or not ... cuz i think this might be another way to know too ... thanks !
hey ah...sorry
I don't really think they like you to email them and ask because my friend called them up and asked about our applications...they just simply said "WAIT"
I think it's not a good practice to annoy them and hand in by yourself will be a great choice to ensure that your application has been received and hopefully be followed.
