There's a couple of ways you could do it, but here's one way:
Create a smart list to pair with your registration form/program. For the filters, add "Filled Out Form" and select the form you're interested in. If you're using it multiple places and only want to know about the results on one landing page, add a webpage constraint and put in the page you're wanting to know about.
The leads tab will now show you only the leads who have submitted that form. If you only want the information from the fields on that form, you'll have to alter your view to show those fields. Then you can use the export function at the bottom of the list (in between the refresh button and search field).
