I recommend you do take the AOW. It does give you a chance to do Five dives with an instructor. It give you a chance to hone your skills with a professional. I would even recommend you continue your education by doing the Rescue diver course. It will give you a much great sense of your own skills. It helped me greatly when I first started diving. Everyone that has posted has given you great advice. PPB, Nitrox, Equipment Specialist, U/W Photo... The list goes on and on. Decide what type a dives you want to do. Maybe you want to take the DPVs out for a spin. You can do that if the shop offers the specialty and has the equipment. You have to decide what your goals are and what you can afford to do based on time and money.
