The provisional answer key often looks final, but a few things can still change before results. Knowing them keeps your expectations realistic.
Questions can be dropped
If a question is found to be wrong or ambiguous, the board may drop it. Marks are then usually awarded to all candidates or redistributed, depending on the rules.
Multiple answers can be accepted
Where two options are defensible, both may be marked correct in the final key.
Your response record is final
What counts is the response sheet, not what you remember marking. Always score yourself from the response sheet.
Normalisation comes after
In multi-shift exams your raw score is adjusted after the final key. A small change is normal.
Both provisional and final keys are listed on the answer keys page of govtpvt.com.
