Should challenges be made more challenging for higher level (platinum status) users?

Question

I'm sometimes a tad bored when doing the challenges. I thought of making it harder, yet still be fair to the beginners.

Answer 2

For example by reducing the time to answer or having the input field not indicate the right answer, i.e. input field shouldn't have a limited length, so the higher level user can't make any assumption whether the input is correct or not.
