Hi, I'm providing the formula to calculate the normalisation of AP EAMCET 2020,

GMS+(TAG-GMS) / (TAS-SMS) * (Marks obtained by the candidate - SMS)

• TAG - Top average global. It is the average mark of the top 0.1% of all the candidates across all sessions together.
• TAS - Top average session . It is the average Mark of the top 0.1% of the candidates in the session in which the candidates belongs to.
• GMS - ( Average + standard deviation) of all the candidates across all session together.
• SMS - ( Average + standard deviation) of the session in which the candidate belongs to.
