For some swimming facilities it is important to bring specific equipment for your use during your lessons. When you sign up for the swimming lessons, find out what types of equipment you need to consider having or investing in for the class so that you are well prepared.
Progressive swimming courses are an important part of the program. If you are considering a swimming program, find out if the courses will be progressive from one level to the next so that you are fully educated the entire time. This way there's no reason to not advance as you need to.
