The third thing in level of importance is to define if you want private dance classes or group classes.
Private classes have a higher cost than group classes, but at the same time you have the advantage of having only the teacher for you.
The teacher evaluates your rhythm and coordination skills and, according to your level, he will create a personalized plan for you.
Group salsa classes are cheaper and on the other hand you can socialize and meet people.
Some dance academies manage socials in their programming. They are meetings where the students of the academy get together to practice while dancing.
