Hey bumblebee!
From what I've read, it seems the destroyer problems are more difficult than the real DAT. Also on the DAT, I don't think you will have the type of calculation problems that are found on destroyer where a calculator would be nice. I'm also doing them right now and I find them pretty challenging, so you're def not alone. This is my first time going through em, but I hear the 2nd/3rd time is much easier. Keep at it!👍
