Hi Buddy,

I am also shocked due to change in trend of Percentile vs marks. But it's due to the reason that most of the students have high marks than usual in that particular session. Since % of students who scored equal to or less than your marks have been decreased in that particular session (than previous trends).

All predictors will come with disclaimers that their prediction is subjected to changes. Trends are again changing this year i guess. We can't bet on predictors 100% but they are useful to plan for a career ahead.

Thank you!
