I want to take a specific class don't see a time that is convenient for me

Don't worry!

If there is a specific class you really want to take but don't see a suitable time you can send a message and request a new time to the teacher by clicking on the  "chat with me" button on the class page. 

(This button can be found under the title and description of the class.)

Once you click this button you will have an option to write and send a message to the teacher. Make sure to check your email and inbox for responses from the teacher!
