"Cake is delicious."

Translation: 케이크는 맛있어요.

[benollier]

Why is "케이크는 맛있습니다" not accepted? I'm 95% sure there is no difference other than formality.

You are correct. This happens on nearly every exercise, so report it every time.

케으크 맛있어요 is not a typo

[thenamtiddies]

why is 케이크가 맛있다 wrong? It says 케이크가 맛있는다 is the correct form, is it some grammatical rule?
