AP EAMCET 2017 Normalization Procedure

Last Updated - April 25, 2017

Normalized score is calculated by considering the difficulty level of each set. Since the questions are different in different sets, the difficulty level of a particular set is different from other sets. Normalization is not done in an exam with only one shift. Further, AP EAMCET Committee has decided to adopt a normalization process to eliminate any such variations in the difficulty level of various sessions. Below is the formula used in AP EAMCET Score Calculation:

AP EAMCET 2017 Score normalization

AP EAMCET 2017 state level exam will be held from April 24 to 28, 2017 in multiple sessions based on the same syllabus, same pattern for candidates having same eligibility criteria. AP EAMCET Admit Card will be issued by the conducting body on April 19, 2017. To download it, candidates have to visit AP EAMCET official website i.e. sche.ap.gov.in/eamcet.

From EAMCET 2009 onwards there is a 25 % weightage for inter marks and 75 % weightage for EAMCET Marks will be used for calculation of EAMCET Ranks. Only Group subject marks will be considered in Inter-weightage.

After aggregating the both Inter + EAMCET weightage Marks final EAMCET Rank will be calculated.


What is Normalization?

Normalization, as used in Indian context, is a process for ensuring the students neither advantaged nor disadvantaged by the difficulty of examinations conducted in multiple sessions. Normalization process ranks all the candidates across all sessions on a comparative scale. In any normalization process, the marks of the easier session may be reduced marginally and the marks of the harder paper may increase marginally on the global level, depending on the average performance in each session. If there is no much difference in the averages between two sessions then there won’t be much difference in the normalized marks as well. Normalizing marks would justify the candidates while protecting their actual performance.


AP EAMCET 2017 Marks Normalization Process

The main aim of the normalization is to justify the candidates who got a difficult paper compared to an easier paper. Hence, the task is to rationalize in a best possible sense and rank the candidates based on the global performance. Various national level examination bodies like JEE (Main), GATE etc. are currently adopting such normalization procedures. Correspondingly, EAMCET committee has deliberated extensively and decided to use the following normalization procedure.

AP EAMCET will be following the below given normalization process to ensure that fair marks will be allotted to all candidates of different sessions:

                          (Top Average Global - GMS)       

       GMS +    _______________________    X (Marks Obtained of the applicant – SMS)

                          (Top Average Session - SMS)

 

SMS: (Average + Standard Deviation) of the session in which the applicants belong to.

GMS: (Average + Standard Deviation) of all the candidates across all sessions together

Top Average Session: Average marks of the top 0.1% of the candidates in the session in which the candidate belongs to.

Top Average Global: Average marks of the top 0.1% of all the candidates across all sessions together.


AP EAMCET 2017 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.

AP EAMCET 2017 Tie Resolution

In case of a tie, the comparison for a better rank would be arrived at by first considering the total marks in EAMCET and if they are also equal, marks scored in mathematics or biology would be the next consideration.

If there is a tie again, marks scored in physics in EAMCET would come into picture and even if they are equal, the total marks obtained in the Intermediate examination would be considered. If still a tie, date of birth of the candidate would be considered and the older one would get preference. Effectively, everyone would be given a separate rank with this method. Another important component of the process is the inclusion of practical examination marks.


AP EAMCET 2017 Result

Marks obtained in the advanced supplementary examinations of Intermediate would also be considered. So, the final rank will be given using the marks obtained in the advanced supplementary examinations. Marks will be taken into account for calculating the rank and final admission would be given based on ranks only.

JNTU will be declaring the result of AP EAMCET 2017 on May 6, 2017. The result will be available for all candidates only in online mode. Along with the scores, the ranks of the applicants derived from the process of normalization of AP EAMCET 2017 marks will also be present in the result.
