Do you mean to say that people who get tutored don't deserve the marks they get?
If that were the case, I guess Olympic medalists don't deserve their silver bronze and gold since they trained and obtained professional help to achieve their best.
No, I'm making no implication as to the value of tutoring.
But I was just questioning why you said "say no to tutoring", implying that others who did get tutored were making a wrong decision as if their choice is any less valid than yours.
Are you sure your report marks are raw? Some schools align their report marks to performance bands and provide band descriptors so that students and parents can get meaningful information about students' achievements.
Of course it's possible, and the decision really depends on the person.
Statistically speaking, 27% of people who got a UAI of 95.00-95.95 did only 10 units.
