I'm impressed by how much ignorance there is here about the SAT. Haven't most
of us taken it?
 
A) You do not get 200 points for signing your name. The test scores just don't
go below 200. If they can't verify who it was that took the test, you won't
receive your score and you'll be out the test fee. Additionally, if you don't
sign the honesty agreement, they won't count it. They will not send a zero
to your colleges.
 
B) Not answering any questions can be better than a 400. I believe the last
couple of "curved" grades are reserved for negative raw scores
 
C) It is practically never a bad idea to guess on the test. The system is
set up so that the expectation value of the raw score you get from randomly
filling out every circle is the same as what you get by filling in nothing at
all. Near the ultra-high scores and ultra-low scores this changes because of
the way raw scores are mapped on to "curved" scores. So if I expect to get
about a 750 on one part of the exam and I have ABSOLUTELLY NO CLUE what the
correct answer is, I should not guess. If I ever have even the slightest
inkling about the answer I should guess.
