I couldn't find anyone who had posted this before so I thought I would ask:
Could I implement a quiz using the quiz add-on with gravity forms and have a payment service at the end?
User is sent to quiz and they fill out the appropriate fields (Name, Email etc...)
User fills out the form
Upon completing they are required to pay using paypal
Upon Success of payment they get sent an email with their results, essentially a customised email certificate.
Also a email sent to the owner of the quiz notifying that "X" has completed the survey and here's the results.
I'm sure this can be done with the Developer Licence but I just need a reassurance it will work in the way I mentioned above.
