As you have noticed we sell hours, not classes, that way you manage the time you purchase as you prefer. How? very simple, your classes don’t have to be of one hour always, you can have 45, 30, 15 minutes classes. We will be counting the time that you have used, and will notify when reaching the 50% and 100%. You will know in every moment how much time you have used too, it will be written in the document of our classes next to the date of every class.
