Did you type a connection that was correct but not get the points you deserved? If so, sorry. The system isn't perfect. Do give yourself the extra points mentally. (There's probably no need to comment about this, unless it's constructive.)
I couldn't work out 3 of the 4 groups.
Then the time ran out, they grouped and I thought I like this.
Thanks for a good grid ANDP. keep up the good work.
