Move the "Apply" button ABOVE the "I have filled out the application" checkbox.
This is comparatively minor, but if a course has an application, an "apply" button shows up. The button appears after the text "I have filled out the application and received approval to register". (I am familiar with this for a Course application for Single Pitch; I'm not sure if it's in other places too)
Placing this in front of the checkbox is confusing: the checkbox is typically directly above, and used to trigger the "register" button. I swear I stared at that page for ten minutes searching for an apply button and entirely missed it.
Consider moving "APPLY" above the checkbox, encouraging the reader to read down the box in order.
This idea is complete! The apply button will now come before the checkbox in the registration box.
