This is one of the worst kind of questions one can come up with.

It's absolutely impossible to turn an average coder into a great coder. Because the things about code you mention in the question -

1. Beautiful 2. Modular 3. Modular 4. Maintainable

All of the four things above do not come by direct learning. They come with experience and a lot of practice.

I agree with the fact that you can make a platform to provide the user with questions that will challenge him but still there will be a part where you will give him some hints. And that will just spoil the entire working.

Don't see why one would call it a bad question.

A bad question is one to which everyone knows the answer to (or everyone knows that no one knows the answer to).

"It's absolutely impossible to turn an average coder into a great coder." - Sorry all great coders were average at some point. No one is born great.

I think what he meant is that it's impossible to "make" someone a great programmer, as in "transform him by applying external force". If so, then I agree - it's impossible to "teach" or "convince" someone to write for example readable code, one must learn on his own through practice.

I think you can turn an average coder into a good one. Just not a average / good one into a great one.

Couldn't agree more. BTW, that's the reason why, contrary to popular belief, old programmers are often better than young programmers.
