How to implement a similar test?

Question

PHP

Help me find the source of similar sites below, I'm sure that the scripts are in the public, because the sites are similar to each other, but it seems that I'm not looking for it or my hands from the same and therefore could not find it.
Websites: testyourbond.site, brotest.ru, quizzer.top

Answer 1

You hardly find it.
Such sites are made on the strength of a few evenings, or even in one, if you use Google forms.
