I wouldn't put too much stock in that score break down. I know other people who have gotten a break down saying they were average or better for everything and they still did not pass. My guess is that there just isn't enough detail of the stuff you really missed, maybe in an attempt to keep people from fully understanding how the exam is graded/scored.
It is possible to not do the written communication and pass, but you would have to do really really well on the rest of the exam. All I am saying is since I dislike the simulations and written communication portions, instead of stressing about them I make sure I focus on doing well with MC. I still attempt all the tabs and the written comm on the exam, but I am hoping to only need partial credit from those areas to pass. And like I said above, 1/3 of the written portion is writing intelligently, with a clear structure, good grammar, and correct spelling. Those are easy "points", so you should always attempt to write something for a communication tab even if you have no idea about the correct answer. Even if you lay out a basic memo outline you will probably get some credit.
