Here’s how it works: your monthly subscription to the UTD Scuba Diving course materials includes every course in your category. If you are taking your first Open Water class, you will have that content, but you will also be able to access the online courses for Nitrox Diver, Dry Suit Diver, Night MINI, and dozens more. Any time you want to take a certification class with your UTD instructor, you’ll have the content. Just study, register, and start your in-water training.
