It should be. I reported it (2019-07-07) along with "Today's quite cold".
Also, the hint for 꽤 is "quite" and "pretty," but the exercise will not accept "It's quite cold today"
Today is quite cold is pretty much a LITERAL translation, and is much more colloquial English
I think I would hear what they're saying if it was a real voice. As it is, I'm just relying on memory.
Same. It's kind of confusing just reading it.. but once you hear it, it makes a world if a difference!
