Create quizzes and flashcard decks using an interactive WYSIWYG editor; record scores

== Description ==
Online quizzes and flashcards for WordPress.  Qwizcards lets you create fill-in-the-blank questions with "autocomplete" suggestion lists.  You can include images, and labels that can be dragged-and-dropped to hot-spot targets on the images.  Qwizcards includes progress and reporting features -- students can log in when they take a quiz, and you can get score reports by student.  See <a href="https://qwizcards.net">https://qwizcards.net</a>

An interactive what-you-see-is-what-you-get (WYSIWYG) "wizard" makes it easy to create quizzes and flashcard decks, and/or you can edit the shortcodes directly.  Online demo: <a href="https://qwizcards.net/wizard">https://qwizcards.net/wizard</a>

In the WordPress Block Editor, open a Classic paragraph or block and click the "Q" icon to get started!  (In either the "Block Editor" or the "Classic Editor" you may have to click the "Toolbar Toggle" icon to see the "Q" - it's in the second row.)

== Installation ==
Dashboard > Plugins > Add New

In the WordPress Block editor, open a Classic paragraph or block and click the "Q" icon to get started!
