Take payment as the first step of a multipage form

We have a multi-page online form/test – which provides a result at the end. Taking the test requires payment. What we would like to do is to collect the initial data like name, email address, phone etc, then get user to pay, and once payment is processed we take them to take the quiz/test.

Currently from what we’ve read its only possible to collect payment at the end of the multi page form in our scenario. Is this correct?

How can we adjust the plugin to collect payment as described above?
