Excellent LMS Plugin

Masteriyo is an easy to use plugin for setting up lessons and quizzes. I use the pro version, and the ability to use fill in the blanks as well as other types of questions, like true/false, and single or multiple choices is excellent.
If an issue comes up, the support team will work on it and fix it.
I recommend Masteriyo for those who want a system that has enough features but is also cost effective.
