Just tested today, and wow... was completely thrown for a loop on the vignette! It was completely different and way more complicated than ANY of the practice versions I've seen thus far... an irregular plan shape with multiple odd-ball framing areas required.
I've done well on my exams thus far, breezing through CDS, BDCS, PPP, SPD & BS on my first attempts. However, I felt really unsure after getting thru the SS multiple choice section and was looking forward to letting my brain relax thru an easy vignette... surprise! Makes me feel like NCARB is intentionally making these last versions of 4.0 extra difficult so people are forced to transition to 5.0...
