hi every one , our team has submitted for Chairman`s award for the first time this year and we have some questions ,
1) we read about the video required for chairman`s award , we have to present it to the judges right ? but when ? in the presentation time ?? which is 10 mints * 5 for presentation and 5 for questions so the video that we have to present to the judges , must be presented in the presentation time ???? (5 mints ) or what ?

2) the vid size have to be max 5 mb?! really ?? thats too small

3) if you know what kinds of questions , the judges might ask us in the presentation time tell us ^.^ and thanks very much.
