Moving On

[CatherineGross]

Why am I being tested on words I have not learned? Why can't I go to the next lesson?

[Luis]

Can you tell us where this happened?

[CatherineGross]

It happens after I complete a lesson. Then because I don't know the words it sends me back to the words I already know.

[Luis]

I am still a bit confused. What do you mean "sends me back"?
