A multiple choice test created on c#

Hi Bee.

You requested a multiple chioce quiz and I delivered.

Check it out. See how I did it.

Include for anyone to download is the project file.

I developed the project using Visual Studio 2017 Community Edition.

VS 2017 Community Edition is free of charge. Anyone can download it at Microsoft's website and starting using it.

Here are some teasers:

If someone were to repurpose this quiz for something else, where would you find the questions and answers so that you could change them.
Leonard Jade Balajadia7y ago
Is there a design for this? I am not able to find it in the file you sent.
Edit: I just found it. Sorry about that. :)
John Rothenberger7y ago
How would you add a print button option to a summary form like this one?

Thank You
