I replied to your comment on my website, but for posterity here, yes, I do think you did a good job for the part about exiting when bestScore > 100. There's nitpicks, but this is fine! It makes sense, and nice use of a select over a send.

I did expect that this exercise would come after the first one though, and doing this on top of a solution to the first exercise is a bit harder. That said, I also don't mean to claim either are impossible. It's just tough to reason about.
