Hello,

If your son's APEAPCET rank is 7167 , then the EWS rank will be mentioned separately on the APEAPCET rank card only if he is eligible under the EWS category .

There is no separate calculation for EWS rank manually. You have to check the rank card or wait for counselling , where EWS category ranks will be considered.

If EWS is mentioned in the application and eligible, the EWS rank will be shown along with the overall rank.

Hope it helps !
