The aggregate imprints for CDS composed exam for Indian Military Academy, Naval Academy and Air Force Academy will be 300 imprints.

The aggregate imprints for CDS composed exam for Officers' Training Academy will be 200 imprints.

The standard of the paper in Elementary Mathematics will be of class 10 level. The standard of papers in different subjects will roughly be, for example, might be anticipated from an alum of an Indian University. The question papers for General Knowledge (GK) and Elementary Mathematics will be set in both Hindi and English.

I) SSB Interview

Applicants who qualify the composed exam should show up before the Service Selection Board (SSB) for a meeting (identity test.) You may need to show up in any of the 3 SSB focuses in India: Allahabad, Bhopal or Bangalore.

The aggregate imprints for SSB round for Indian Military Academy, Naval Academy and Air Force Academy will be 300 imprints.

The aggregate imprints for SSB round for Officers' Training Academy will be 200 imprints.

The SSB shortlisting comprises of two phases led over a sum of 5 days. You have to qualify in stage-1 keeping in mind the end goal to further to stage-2.
