RNAA

I am a new Educator in a big teaching University. My Education Coordinator have ask me & 3 of my colleagues to develop a program to train 400 second year nursing students to learn "first aid" with in 2 days, from 9 to 4 pm each day. There is a big auditorium that can be divided into 4 sections, complete with big screen and all audio divices. They have divided all the topics for "first aid" into 4 of us. Now how to deliver our lectures within the given time with this huge number of students without any much disturbance from each other. How are we going to shift from each section without delay and that all 4 Instructors will conduct their own lectures assigned and shift from one to the other without much noise. Any tips and anybody who have the same experience that you could share will be very much appreciated. Thank you.
