This page gives you information about the class, including the intended size for the class and how many spaces remain.  To register for the class, click on the blue button at the bottom right of the page that says, “Add to Cart”.

After you click, an additional button will appear ("View Cart") that will take you to your shopping cart which contains this class and any others you have chosen. You can click if you like, or you can click on the button at the bottom left that takes you back to the list of other classes.

Note: You can only choose the class once.  If you click "Add to Cart" an extra time, a second class will not be added and a reminder message will appear.
