Hello Aditya,
As a PCB (Physics, Chemistry, Biology) student after your 12th board exam, you cannot directly appear for the Combined Defence Services (CDS) exam because it requires a bachelor’s degree. However, here’s a clear and concise guide on how you can prepare for and give the CDS exam after completing further studies, tailored to your background:
-
Understand CDS Eligibility
: The CDS exam, conducted by UPSC twice a year, recruits for the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), and Officers’ Training Academy (OTA).
-
Educational Requirement
:
- IMA and OTA: Any bachelor’s degree from a recognized university.
- INA: Bachelor’s degree in Engineering.
-
AFA: Bachelor’s degree with Physics and Mathematics at 12th level or Bachelor of Engineering.
-
For PCB Students
: Since you don’t have Mathematics in 12th, you’re eligible for
IMA and OTA
after completing a bachelor’s degree (e.g., B.Sc., B.A.). INA and AFA are not an option unless you pursue an engineering degree or have Mathematics at the graduation level.
-
Age Limit
: 19–25 years (varies by academy; check upsc.gov.in for 2025 details).
-
Educational Requirement
:
-
Steps to Prepare After 12th
:
-
Pursue a Bachelor’s Degree
: Enroll in a degree program (e.g., B.Sc. in Biology, Chemistry, or related fields, or even B.A.) to meet CDS eligibility. This takes 3–4 years.
-
Apply for CDS During Final Year
: You can apply for CDS in the final year of your degree, provided you complete graduation before the training starts.
-
Application Process

For IMA/OTA
: Written exam includes English, General Knowledge, and Elementary Mathematics (Maths is optional for OTA).

PCB Advantage
: Your Biology and Chemistry background helps with General Knowledge (science sections). English preparation is manageable with practice.
