Hi hikamikubo,
To answer your immediate questions: NO - Business Schools will not see if you 'cancelled' a Score nor will the Schools know which other Schools you chose to send your Official Score Report to. In general, Business Schools do not care if you take the GMAT more than once. However, if you are concerned about this issue, then you do not need to select any Schools when you take your Official GMAT (but you will end up needing to pay a fee to send your Official Score Report to EACH School later on).
In one of your earlier posts, you noted that you were planning to take the GMAT on November 14th and that your Score Goal is 730+. Is that still your planned Test Date and Goal? In addition, have you taken any practice CATs/mocks over the last few weeks? If you have, then how did you score (including the Quant and Verbal Scaled Scores for each Test)?
GMAT assassins aren't born, they're made,
