Presentation

I was expecting our group's presentation for Online Advertising will be held in Week 5, when our lecturer step in the classroom I was expecting lecturer will ask the groups to come out. But, lecturer was  teaching his slide in front. I tough lecturer has forgotten about the presentation. Surprising , just before the class end, lecturer told us there will be not presentation in Week 5. So, we have to present it on Week 6. Good Luck for all presenters.
