No. You should not fill Central EWS using a State EWS certificate. For CUET PG , only Central EWS is valid. State EWS is not accepted . Your form will not be rejected now, but during counselling or admission , if you fail to show a Central EWS certificate , your EWS claim will be cancelled and admission may be affected. Best option: Fill the CUET PG form as General category . Apply under EWS only after you receive the Central EWS certificate . This is the safest way to avoid any problem later. Hope it helps !
