In general I don't think that for a few questions they would change those marks and bump your study score up. The only times I have seen that study scores have changed is when there are clear errors such as whole pages being not marked, errors in scanning of exams or sac ranks/scores being inserted incorrectly into the database.
You should remember that exams get marked by two different examiners and if there is a significant difference between their marks it gets marked by a 3rd examiner
I think if someone was getting 3/4 marks or something like 5/6 marks for a question it is unlikely that they would bump that up to 4/4 or 6/6. I believe if you are able to get a paper remarked they remark the entire paper so it is possible for your score to remain the same, go lower, go higher
