I reckon many of these people may be extending on the truth. If they are doing that much study, wasting away their youth, and don't get 100 UAI then what did they achieve. Sure you can be a determined, high-achieving person, but when do you draw the line? Also, Miss_gtr remember schools set different standards of tests/exams/assessments so your 80 might be 'better' than someone else's 95!
