Separating Questions With Header

I hope everyone is doing well and healthy. My client would like to separate the fields something like this:
Part 1
q1
q2
q3
q4
Part 2
q5
q6
q7
q8
part 3
q9
q10
q11
q12

I have tried making more than one quiz and putting in on a single page, but that doesn’t work because each test is submitted separately. I cannot find the documentation for multiple pages, which I really don’t want to do anyway. I would like the have the test/survey questions on one page but broken up by fieldsets.

I attached a sample of what I want to do. The code would look something like this:
<fieldset><legend>Part 1</legend>
<label for=”one” id=”one1″>One: </label> <input type=”text” name=”one” id=”one” value=”” placeholder=”one”>
</fieldset>
<fieldset><legend>Part 2</legend>
<label for=”two” id=”two1″>Two: </label> <input type=”text” name=”two” id=”two” value=”” placeholder=”two”>
</fieldset>
<input type=”submit” value=”Submit”>

My form looks something like what I have attached:
–Part 1———————-
One: _______________
——————————
–Part 2———————-
Two: _______________
——————————
