No one can tell you that without more context - every medical school is different and marks differently and will have a different pass mark for assessments. And each year there will be a different spread of marks, so the only person who can tell you how well you’ve done in relation to your cohort on this specific exam will be your medschool. Presumably they will issue decile ranks at some point? If your mark constitutes a pass, then well done, that in itself is a great achievement and you should be proud of yourself 😊
