The presentation of C class

Last class, we were audience. Presenters were Tomei sensei's students.
I'll give them advice about their presentation. First, you had better prepare for your presentation. Some groups didn't have thier photo and poster. Why don't you bring your information a lot. Second, Don't read. Not all but many read their note or something all the time they were presenting. Eye contact please. Third, please enjoy your presentation. Most of the students seem unenjoyable. Do more active.
This is what I want to give advice.
