I appreciate your effort to make that quiz. It's a nice idea and I pretty much like your GUI.

A big drawback is the quality of your questions, but I'm sure, that you are improving them over time.

I personally prefer questions, which need knowledge of the language itself (e.g. "what does ... print") over questions, which need "meta knowledge" of the language (e.g. what does XYZ stand for). But I have to admit that the Perl ecosystem is quite overwhelming and understanding the community is one very important key to learn the language.

I hope you keep up that work and provide questions for more experienced developers very soon. Thanks for your time and sweat.
