I can say I predicted 4 deaths, 3 ships (still not sure about the fourth one), 1 of my theories was right, everything else was a complete disaster I didn't guess anything, that's why I loved the book - it was a surprise for me, so I really want to thank JK for doing this amazing job.

The plotline was tricky as well, where did they get so many?.. oh, nevermind
Oh, and I knew there would be more Pensieve scenes which was a relief to me
