Is there any way to order a quiz result on last page.

I have a form which generate 8 different numerical values and I want to put it in descending order. Is there any way to do it?

If you want the form fields to automatically arrange in descending order, then that would not be possible. But it is possible to sort them after submission of the form.

You can create a Grid listing report which allows you to sort the fields. Here please check this related guide: How-to-Create-a-Grid-Listing-Report  

OR you can download the submissions in excel and then sort manually - How-to-Download-Form-Submissions-as-Excel-CSV-PDF
