Let's get one thing very clear: there is no score that will automatically 'make' a character a Mary Sue/Gary Stu, a high score only indicates that there might be a problem with a character. This test is for people who are worried that their characters might be Mary Sues/Gary Stus; the intention is to help people to improve their characters, NOT to make people feel bad about them. So if you like your character, that's the important thing. But if you're worried about your character, and are unsure if they need further work or not, hopefully this can help.
