The Rank iQ gives you a real-time analysis of your Rank which keeps getting updated as the number of students using this predictor keeps getting increased.So students are advised to check their ranks again after a certain time interval to know their updated rank.

Let's say topper has 127 marks, so his rank is 1.
Now, there are three students with 126 marks, then all of them will see their rank as 2.
The student with 125 marks will see his rank as 1+3+1=5.

No. Each student is given a unique Id to avoid any duplication. Hence, even if you check the marks with response sheet multiple times, total students don't change.

Normalization score is calculated in case of multiple shifts. Calculation varies as per exam conducting authority. Whichever is the exam, normalization score is calculated as per the formula given by exam conducting authority..
