This is a very awkward English translation. I had to guess at what Duo wanted because I couldn't construct a natural sounding sentence from the word bank. (And of course I got it wrong:)
I asked DL to approve my translation: "Again, I remain the last one".
"I am last again" or "I came in last again." Logically, if you "remained" last, how could this be repeated? Wouldn't you merely extend the time?
