I skipped the last few conceptual lessons on hash maps because it wasn't helping me at all. I'm going to try to figure out things as I go along and go back to those lessons as a reference. I did the Blossom project, but I need to really see how this is used to understand it better. I did the exercises on trees which makes a lot more sense to me, so that's good. I then did the CYOA Wilderness project, so it makes even more sense to me since I'm so obsessed with interactive fiction. Next up is heaps, which look like reversed trees?
