Have a question related to CDS ?
Dear Candidate,
You are eligible for CDS 2026, but for IMA, INA and AFA post, you must be born between 2 Jan 2003 – 1 Jan 2008.
For OTA ( male and female ), all 2003 born candidates are eligible.
Hi dear candidate,
The age limit for various roles in CDS are:
1) IMA: 19 to 24 years of age, 8 to 9 attempts.
2) INA: 19 to 24 years of age, 8 to 9 attempts.
3) OTA: 19 TO 25 years of age, 10 to 11 attempts.
This is all considering your DOB as of 26 Oct, 2005 as you are 19 years old in Aug 2025.

BEST OF LUCK
Yes, you will be eligible for CDS-1 2027 under OTA (SSC Women – Non-Technical Course). The age limit for OTA is 19–25 years (you must be born between 2nd Jan 2001 and 1st Jan 2007). Since your date of birth is 4 July 2002, you will be 24 years old at that time, so you fall within the required age range.
But you will not be eligible for IMA, INA or AFA, because their upper age limit is 24 years, and by 2027 you will cross that limit.
As per the CDS OTA eligibility criteria, for female candidates applying to the Officers Training Academy (OTA), the age limit is 19 to 25 years (unmarried females only).
Since your date of birth is 16th June 2005, you will turn:
21 years old in June 2026,
25 years old in June 2030.
CDS exam is conducted twice every year, so you’ll be eligible from the year you complete graduation (2026) till you turn 25 in 2030.
Your eligible attempts:
CDS 2 2026
CDS 1 2027
CDS 2 2027
CDS 1 2028
CDS 2 2028
CDS 1 2029
CDS 2 2029
CDS 1 2030 (maybe last)
So, you will have around 7 to 8 attempts to appear for CDS OTA before you cross the maximum age limit.
Hello ,
If your goal is to appear for CDS Exam, then here’s what you need to know:
- For IMA, INA, and AFA: A regular full-time degree from a recognized university is required. So, regular B.Tech is perfectly valid.
- For OTA : Any recognized Bachelor’s degree (even BCA) is acceptable. But since you mentioned Online BCA, note that CDS does not accept distance/online degrees unless UGC-DEB approved and equivalent to a regular course.
So, a regular B.Tech is a safer and more accepted option for all CDS branches. Online BCA may work only if it's recognized, but always double-check the latest UPSC CDS eligibility rules before applying.
Best wishes !
