Is there a possibility that the SAT incorrectly graded your SAT test? You know how those scan-tron machines sometimes malfunction and it goes by without notice? Is this scenario possible for the SAT tests as well?
Sorry for the double post, but i can almost never erase an answer completely. There's always some hue on the bubble, but if i bubble in a different answer darkly; is it possible for the machine to mark the "erased" answer as mine?
Although this does happen, it happens in very rare instances. Remember, if they hand score your test and it turns out that you got marked correctly for one you got incorrect your score can still go down.
