Yapa Capa is an interesting site that is a 100% free for teachers and students. This is a site that allows teachers to create: quizzes, surveys, tests, etc. Teachers can then use the online assessment tools to grade and analyze student's work. This is a very fun and engaging site which is a great way to do online assessments.
I highly recommend checking out Yapa Capa by clicking here!!!
I recommend checking out Gnowledge for a similar type site.
