⁉️🤔 Frequently asked questions

How does an exam plugin differ from a regular quiz plugin?

An exam plugin adds mechanisms critical for testing: timer with auto-confirmation, scoring system with grades, question bank with random selection, protection against retaking and certificates by results. A regular quiz plugin may not have any of these components, it is tailored for viral quizzes and surveys, where accuracy of calculation is not critical.

Can free versions be used for a real exam?

Yes, if the exam is linear and does not require certificates. HD Quiz gives a timer and page-by-page navigation for free. Quiz Maker in the Lite version includes 7 question types, question bank and randomization, this is enough for a test or quiz. If you need a certificate or data export, look at the Pro versions of Quiz Maker or QSM.

Which plugin to choose for a school with classes and students?

There is no direct successor to SakolaWP on WordPress now, the school management niche has gone to full-fledged LMS. For a school with classes and roles (teacher, student, parent) take a bundle: LearnPress or Tutor LMS as an LMS foundation, and Quiz Maker or QSM as an exam engine. Both LMS plugins integrate with Quiz Maker through shortcodes.

Do these plugins support integration with email services?

Quiz Maker (Pro) and Quiz and Survey Master (Pro) can send personalized emails with test results. Watu Quiz in the free version notifies the administrator about test completion, and through an addon bridge connects to Mailchimp. HD Quiz and Chained Quiz have no email integrations, they are purely frontend tools.

What to do if the plugin conflicts with my theme?

The conflict manifests as a JavaScript error, the "Submit" button doesn't click or the test doesn't load. Open the browser console (F12 → Console) and look at the red lines with the error description. As a rule, temporarily disabling other plugins and switching to a standard theme helps, so you isolate the culprit. All plugins from the selection are tested with block editor themes and classic themes, no problems noticed.

What to install in 2026

The choice of an exam plugin comes down to three scenarios. Need maximum functionality out of the box and budget is not tight, take Quiz Maker: 7 question types in Lite, timer, question bank, and in Pro, certificates and CSV export. Doing quizzes, surveys and exams mixed together, Quiz and Survey Master will cover everything with one installation, and 40,000+ users confirm this. Want it free and without compromises on the core, HD Quiz gives a timer and page-by-page navigation without upsell.
