How much time should we spend on KneoWorld?

First, don't feel like you have to push your student through each lesson in 5 days.
Each learner is different! Some might want to work on KneoWorld lessons 5
minutes a day, and others might want to do more. Just note where you leave off
everyday, and when you return the next day do a quick review and start again.
You know your student, do what is best for them and for you.
The pace is up to you and your student. You know what is best for your student.
