Is there any way to undo a lesson skip?

Question

I tried the test without having really started the lesson and somehow won. I'd like to get back to blue (with the progression bar and all that).

Answer 1

There's no way to undo it to my knowledge (without starting a new account), but there's absolutely nothing wrong with backtracking (or in your case, just staying behind), in order to understand and perfect things you have learnt.

Admittedly the actual course questions could be a bit trickier to ensure you fully understand it, but as long as you understand the concepts and know how to apply them, then that lesson has done it's job!

If you have an further questions about that particular topic, you have forums like this, or any on the web such as Stack Overflow which are full of brain-boxes to answer any questions you may have :)
