Same as what everyone else has been saying, easy MPC, except the binary/number systems question. FRQ was difficult to understand. I myself took lots of extra paper to work it out/model it when I solved it, but then I was looking at the pdf on a screen and didn't have it printed out, so I didn't know how much room I had on to work it out on papers given to students. One kid said the make-up FRQ was easier than 2016 (he took the AP Spanish test on May 3, so had a bit more time to study and studied the released frq).
Maybe have more problems that use multiple topics in one problem. I started just programming the released FRQs into my custom content, so kids could work on those in the CodeHS system with autograding, but I didn't leave myself enough time in my pacing to have students finish all of them, so maybe when I next teach APCSA can I plan for that a bit better and intersperse them throughout the year.
I think if I had those ready to go, and pushed students to those, instead of Pokemon or even Elevens/Magpie they might have felt more ready (i.e. a program they can complete fully in less time, instead of weeks long projects).
