I was surprised when my 1/6 gave me high risk. I am very thankful for what I do and I enjoy going to work.
If you answer "None" to everything, your burnout risk is low (0/6).
Answering a single question with 1 (A few times a year or less) puts you at .1/6 (Mid), which goes up to .5/6.
I find the results reporting of this to be rather sensationalist and the whole thing pretty useless. If you're burnt out, you probably don't need an online quiz to tell you.
I scored 3.4 and got mid. When I read the parents comments I thought that might have meant a lower score was higher risk. I suspect it depends on the categories you answer.
