The idea is that there isn't always just one "next" option, thus the idea would be to go back to the flowchatt to choose your next lesson. However, there's probably many (like you!) who just want to be taken to the next lesson and not hassle with the navigation - great input.

Thank you! I'm sure this is something that could be improved.
