I like to pass different tests. And you? Offer something interesting.

What do you mean by tests? You are looking for assignments? or you want to create a 2 option test and see which one works better?

As an exam unfortunately I can't help, but if you do want to try create two different options and check which one of them works better, I would try to consider using Twik. It's a personalization tool that helps to increase conversion by presenting each user the best version out of the two that will most likely help the user convert.
