Is this answer really wrong: If yes, so much better?

i guess there are still things being improved with this program." If yes, so much the better" should be accepted. It's a direct translation. There's only so much one can expect from learning this way. I still think it's fantastic.

"much better" is OK, "so much the better" is OK, but "so much better" is completely wrong! Pourquoi?

wierd english is there a better translation

"Si oui" appears to be a colloquialism used in certain contexts. I propose Duolingo update the definition when one mouse-hovers over the pair.

I think it's grammatically incorrect. Never heard of "so much the better" before

This translation is bad. It's almost a guaranteed incorrect answer.

"if so, so much ¿THE? better" It'd be perfect English but sure sounds like hell and I've never heard it like that before in my life...
