I manage in person training courses.

My CRM has a list of participants/contacts

I have a module called 

Course Types
Course A

Course B

Course C

I have another module called Scheduled Course - These are the courses we have scheduled.  Scheduled courses and Course Types are connected
Schedule Course 

Course A: Section 1: 

Course A:  Section 2

Course A: Section 3

Course B:  Section 1

Course B: Section 2

Course B: Section 3

I have another module called Enrollment

That creates a new record for the contact and shows them as either registered, or course completed in relation to the Schedule course module

After each completed course I want to use a zoho form and ask the participants what their interest in the other types of course we offer.  So I have a form that asks are you interested in:

Course A

Course B

Course C

I use check boxes on the form.  

How do I integrate the collection of data from the zoho form into my crm in relation to course type.  I would like to eventually have an automation that changes the status from interested in the course type module to registered in the scheduled course module.
