> - Within the grammar questions, Choice (e) "None of the above" is 99% of the time NEVER the answer.

This is exactly the reason that, when I design tests, I strive to make "none of the above" or the outlier answer the correct one about 20% of the time. I really hope the SAT writers are doing that now.
> ALL sections (and sub-sections) have questions that strictly increase in difficulty / projected "miss-rate" as time goes on.
The computerized GRE goes even further... it's like a videogame, it feeds you harder questions the better you do, then reverts to easier ones when you mess up.
