When you click on the "Update Account" link you are brought to a page with a form containing all the information you entered in when you registered. From here you can change this information. Simply click in the field you want to alter, make the changes, and then click on the "Update" button along the bottom. The "Reset" button will remove any changes you have made since the last save.
Occasionally, the computer may catch a mistake that has been made on a form. When this happens, the next screen will be the same form with a message written in red. This message will explain what needs to be corrected. Once all of the errors are corrected, you can click on the "Update" button again and your account will be updated.
Important: If you wish to change the number of students you have, you must do so from the Update Account page.
