Multiple Forms to One Table

Hi! I’m building an interactive course and I’m trying to understand how multiple forms can write data to one record instead of creating new ones.

I have a Class table with fields like Question 1, Question 2, Question 3, etc.

Throughout the lesson, I placed multiple single-question forms between content sections.

My goal:

When the same logged-in user answers each form, all answers should update one single row in the Class table.

What’s happening now:

Each form submission creates a new row, instead of updating the existing user’s record.

Is there a way to have multiple forms update the same record?

Do I need to connect the forms to a user record, record ID, or lookup field?

I’m a beginner, and would be satisfied if your answer included keywords or concepts I should research even if you don’t know the answer. That would help a lot. Thank you!
