My experience with these in-class group presentations is that most groups tend to shut out the presentations of the other groups because they're focused on waiting for their turn to present and last-minute prep. So unless it's a really good presentation most of them probably fall on deaf ears. Now these students will present a company pitch for a company that wants to actively recruit students from the class. I'd probably listen to that.
