Is it bad I never get these challenges correct but usually end up studying the solution?

Not bad at all, It's what makes us focus even more. Until we have it right in our minds, so it works out!

Just joined this myself and it's been nothing but fun so far.

Same here, Rich. I usually get the basic challenge right, never the "go even further..." part.

But here's the thing. It feels to me that as much more training we do, more suited our brain is in order to understand challenges in a way we can actually feel confident to get the answers right.

So what i mean is, as much practice we do, the more our brains knows the way to a solution. Maybe something to do with muscle memory and lack of a fear for things, because it's not as new as it used to be anymore.

So i guess the answer is practice and trust in the process.
