Hello aspirant

hope you are doing well and safe. With reference to your query,  I would glad inform you that minimum age to give cds exam is 19 years and depends on fields like air force , indian military academy maximum age limit varies around  22 to 24 years . According to your dob ,you will turn 24 in 2027 , so you can expect 2027 will be the last attempt year for cds exam in your case

Hope you found this answer informative. Best wishes for your future
