Well, much to my surprise, I've finished. Much harder than last week. But there are a lot I cannot fully parse.
As I said before, FOI was 16ac, LOI was 13ac, COD like many of you was 26ac. But I also liked 10ac, 21ac and 20d.
Unparsed or not fully parsed:
1ac, 24ac, 1d (I can see the symbol), 2d (where does the half-hearted course director come in?), 7d (though maybe I just need to reverse the answer?), 17d ( a bit obscure for me - I didn't know that abbreviation of champion), 18d (where does the boring puzzle come in?), 23d. I didn't like 14ac either (met for satisfied?)
I found I had to work out the definition and then look for the parsing.
