I’m going on vacation next week and we plan on going scuba diving but i’ve never done it before. I’m a good swimmer but what can i do to be a good scuba diver!

Since you’re not certified, and you didn’t mention that you’re taking a class, I’d say you will be doing what’s called a Resort Dive. You will be with a certified instructor the whole time and will probably be less than 20 feet down.

Mostly, relax and have fun. Your instructor will tell you everything you need to know.
