Weightage for assigning merit ranks:AP-EAMCET-2017

Weightage for assigning merit ranks:

75% of EAMCET normalized marks and 25% of Intermediate Marks in group subjects to prepare the rank.
Note:

For the candidates for whom there is no qualifying cut off in AP EAMCET - 2017, if the marks in AP EAMCET – 2017 after normalization goes below zero (negative), the marks is treated as zero and the rank is assigned based on 25% of Intermediate marks weightage. If the tie persists, then AP EAMCET – 2017 normalization marks (though negative) are considered for breaking the tie.

Demonstration with a sample data:

The following is based on a sample data to explain the normalization process. The data is based on almost equal number of candidates in all the four sessions. The normalization is shown subject wise so that students get the benefit based on subject wise performance rather than the entire paper in a session.

Averages and Standard Deviations in a particular session and averages of top 0.1% candidates of a particular session, Global Average and Standard Deviations of all sessions together, Averages of top 0.1% candidates in all sessions is given in Table 1. Example data of normalized marks is shown in Table 2 to Table 5.
