You can assign grades and point levels for every grade in the exam / quiz. Then assign points to every answer to a question and Watu will figure out the grade based on the total number of points collected. Watu for WordPress is a light version of <a href="http://calendarscripts.info/watupro/" target="_blank">Watu PRO</a>. Check it if you want to run fully featured exams with data exports, student logins, categories etc. **This plugin is mobile / touch - friendly.** The quizzes will work on mobile devices and phones. **Please go to Watu Quizzes in your dashboard to start creating quizzes and exams.** ### Features ### * Creates quizzes, tests and exams * Use shortcodes to embed quizzes in posts or pages * Single-choice questions * Multiple-choice questions * Open-end questions (essays) * Required questions * Randomize questions * Pull random questions from a pool * Grades * Shows answers at the end of the quiz or immediately after selection * List of users who took exam along with their results * Export results to CSV file * Ajax-based loading of the quiz results * Facebook sharing * Mobile / touch - friendly * Notify admin when someone takes a quiz * You can connect to MailChimp using the [Watu to MailChimp Bridge](https://wordpress.org/plugins/watu-bridge-to-mailchimp/ "Watu to MailChimp Bridge") * A basic bar chart is available for showing user points vs. average points on a given quiz ### Attention WordPress Network (Multi Site) Users ### When activating the plugin do it as blog admin and not as network admin. ### Online Demo ### Feel free to check the [live demo here](http://demo.pimteam.net/wp/?p=12 "Live demo"). It should answer most "pre-download" questions. If you have more doubts just download the plugin and check out if it works for you. It's free and takes a few seconds to install and activate. ### Troubleshooting ### **When opening a support thread please provide URL (link) where we can see your problem.** A very common problem is not being able to submit the quiz, or the quiz does not displays at all. This is usually a fatal JavaScript error caused by other plugins or your them. If you are technical you can easily find the error yourself by checking the JavaScript error console in Chrome or Firefox. Disable the offending plugin and everything will start working normally. ### Developers API ### In order to allow other plugins to integrate better to Watu we have started working on developers API. The following action calls are currently available: = do_action('watu_exam_submitted', $taking_id) Called when exam is submitted, passes the attempt ID = do_action('watu_exam_submitted_detailed', $taking_id, $exam, $user_ID, $achieved, $g_id) Same as above but passes also the full exam object, the user ID, points and grade ID = do_action('watu_exam_saved', $exam_id) Called when you add or edit exam (after submitting the changes). Passes the changed exam ID. ### Community Translations ### * Persian (Farsi) translation provided by [Reza](http://iksw.ir/): [download zip](http://blog.calendarscripts.info/wp-content/uploads/2015/12/watu-fa_IR.zip) with .po / .mo files * German translation provided by Peter Baumgartner is available [here](http://peter.baumgartner.name/goodies/uebersetzungen/watu-deutsche-uebersetzung/) * Russian translation provided by @Nikon: [.po](http://blog.calendarscripts.info/wp-content/uploads/2016/02/watu-ru_RU.po) / [.mo](http://blog.calendarscripts.info/wp-content/uploads/2016/02/watu-ru_RU.mo) == Installation == This section describes how to install the plugin and get it working. 1. Upload the entire folder `watu` to the `/wp-content/plugins/` directory 1. Activate the plugin through the 'Plugins' menu in WordPress 1. Go to "Watu Settings" to change the default settings (optional) 1. Go to "Watu Quizzes" under "Tools" menu to create your exams, add questions, answers and grades. On the "manage questions" page of the created exam page, above the questions table you will see a green text. It shows you the code you need to enter in a post content where you want the exam to appear. == Frequently Asked Questions == = How are grades calculated? = Watu computes the number of points in total collected by the answers given by the visitor. Then it finds the grade. For example: If you have 2 questions and the correct answers in them give 5 points each, the visitor will collect either 0, or 5 or 10 points at the end. You may decide to define grades "Failed" for 0 to 4 points and "Passed" for those who collected more than 4 points. In reality you are going to have more questions and answers and some answers may be partly correct which gives you full flexibility in assigning points and managing the grades. = Can I assign negative points? = Yes. It's even highly recommended for answers to questions that allow multuple answers. If you just assign 0 points to the wrong answers in such question the visitor could check all the checkboxes and collect all the points to that question. = How do I show the quiz to the visitors of my blog? = You need to create a post and embed the exam code. The exam code is shown in the green text above the questions table in "Manage questions" page for that exam. **Please do not place more than one code in one post or page. Only one exam will be shown at a time. If you wish more exams to be displayed, please give links to them!** = How does it handle user accounts? = Watu uses the WordPress user registration / login system. So if you want to allow users to register for quizzes simply select "Require user login" in the Edit Quiz page and make sure "Anyone can register" is selected in your WordPress Settings page. = Is it compatible with BuddyPress or membership plugins? = Since it uses the standard WordPress user login system, it is compatible with BuddyPress and all membership plugins that we know about. Of course, some odd membership plugin that uses its own user login system might be incompatible with Watu. = How to translate the plugin interface in my language or just change some of the texts = You can use the standard WordPress way of translating plugins (via Poedit and .po / .mo files) or use plugin like Loco Translate. If using Poedit, your file names should start with "watu-". For example: watu-de_DE.po / watu-de_DE.mo. They should be placed in wp-content/languages/plugins folder. = Can I override the templates / views without modifying the plugin code? (For advanced users) = Yes. You can create a folder called "watu" under your active WP theme folder. Then create a copy of the view file you want to modify, keep the original name, and place it in the "watu" folder there. (Do not create "views" folder). Then the copy of the template will be used instead of the original one. == Screenshots == 1. List of your exams with shortcodes for embedding in posts or pages 2. The form for creating and editing an exam/test 3. You can add unlimited number of questions in each exam, and each question can of single-answer, multiple-answer, or open-end type. == Changelog == = Changes in 3.0 = - The plugin will now count empty (unanswered) questions separately from wrongly answered.
