I am really surprised by the way the expected score is changing in Pragy's App. I'm not asking if it has duplicate entries or anything like that, I know that the predictor is legit. However, what I'm concerned about is the expected score. My expected score goes down by some margin as and when someone with higher marks than me checks his/her response sheet. On the other hand, the reverse is not true. It doesn't increase by any margin (let alone significant) when the number of people who have lower marks than me increase.
I just want to know if there is a chance of deviating from this expected score, and by how much? Will it even increase anymore? Or it will only go further down as the number of people ahead of me increase?
