Ronc98 is correct in saying the pool sessions are preparing you for the open water experience. You will learn about buoyancy control, regulator and mask recovery, out of air emergencies. navigation, decompression, ect... These are all things you really need to be comfortable with and understand.
One thing people often assume about diving is its a 'macho' sport. To be honest, its far from that. Its more about being relaxed and having a good time seeing the things underwater. There is no competition to be a 'better' diver than someone else. You dont need to be an olympic swimmer or a fitness freak, but you do need to be comfortable with your own abilities. If you think a dive is going to to be more than you are comfortable with, dont do it- thats how people get hurt on scuba. There is no shame in calling off a dive.
