There're two ways to do it:
Method 1
1. Create a general submission form for scholarship application
2. In form settings, set the redirect for this form to the ticket purchase form, so user is redirected to purchase form on submitting the scholarship application, and completes the ticket purchase.
Method 2
Workflow: User goes to ticket purchase form > Completes the purchase > Goes to Update profile page by clicking on the Update profile button > Updates the information related to Scholarship role.
