Failed BDCS because I failed the roof vignette, which I thought at the time was pretty easy. My guess is I ran out of time (spent way too long on stair vignette), and made a calc error that I didn't catch. Because I couldn't make equal sized gables so maybe I calculated one slope wrong because I was moving too fast? I don't really know. Left the test thinking I had failed the stair but ended up failing roof (and passing the stair)! Maybe I missed something else? I'm posting my practice here for review.
Comments appreciated! Thanks!
