Shouldn't this also accept "I'm not ready"?

The exercise should also accept "I did not get ready!"

"I'm not ready" is this an acceptable translation?

"I have not prepared" and/or "I didn't prepare" are literal translations, but not really correct, as "have" demands normally an object in English. "I am not prepared" would be the better translation if there is no object.

Slogan for this course tbh ^_^

The last one didn't accept “Are you prepared” and this one doesn't accept “I'm not ready” . Frustrating

"I am not prepared" was not accepted. It is a correct translation. Please fix
