    AP EAMCET Normalization Procedure - How to calculate Final Marks?

    AP EAMCET is conducted in multiple sessions each year. For this year, the exam is scheduled from April 22 – 26 in online mode. Candidates can appear only in one session based on same AP EAMCET Syllabus. It is obvious that the comparison of question paper will be done by the candidates.

    However, to maintain equality among the candidates a normalization procedure is introduced by JNTU Kakinada. Below is the formula used in AP EAMCET Score Calculation:

    AP EAMCET Normalisation Procedure, AP EAMCET Normalisation of Marks

    SMS: (Average + Standard Deviation) of the session in which the candidate belongs 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

    Note: From EAMCET 2009, a 25 % weightage for inter marks and 75 % weightage for EAMCET marks will be used for calculation of AP 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 in the examination simply means calculating scores of each candidate with fair means.
    • It is a process of 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.
    Note: Various national level exams like GATE, JEE Main, CAT etc are adopting the normalisation procedure.

    Weightage for Assigning Merit Ranks

    AP EAMCET Rank is prepared by considering 75% of EAMCET normalised marks and 25% of Intermediate marks in group subjects (PCM/ PCB).

    • For candidates having qualifying marks in AP EAMCET, if after normalization, the marks in any individual subject(s) become negative, then the normalized mark(s) in the respective subject(s) are treated as zero. However, total marks in three subjects are considered as EAMCET marks.
    • For SC and ST candidates, having no qualifying cut off in AP EAMCET, if the marks in all the three subjects after normalization go below zero (negative), the total marks is treated as zero and the rank will be assigned based on 25% of Intermediate marks weightage.

    AP EAMCET Demonstration with Example

    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.  Normalization is indicated 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.
