Hi Arjun,

UPSC conducts the Combined Defence Services Exam twice every year. Candidates have to meet different eligibility criteria to appear for the test. The maximum age limit you can apply under CDS Examination is of Officers’ Training Academy and that upto 25 years. This is the maximum age limit beyond which a candidate is not all allowed. Hence you will be eligible to apply for CDS till somewhere by 2022.

PS.: All other posts have maximum age limit less than 25.

All the best.
