CDS Eligibility Criteria 2025 – Age Limit, Qualification, Nationality

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:

1. 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).
     
     
2. 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 :
     
     
     • Visit upsconline.nic.in when notifications are released (typically December 2024 for CDS I 2025 and May 2025 for CDS II 2025).
       
       
     • Fill out the form, pay the fee (Rs. 200; exemptions for SC/ST/females), and select IMA/OTA as your preference.
       
       
3. CDS Exam Structure :
   
   
   • 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.
     
     
   • Challenge : If you’re weak in Mathematics, focus on OTA, where Maths is not required, or practice basic 10th-level Maths for IMA.
     
     
   • Next Steps : Clear the written exam, then pass the SSB interview and medical test.

To prepare for CDS, CGL, and CAT during graduation, create a clear study schedule focusing on basics, reasoning, and aptitude. Practice daily mocks, improve time management, and stay consistent. Balance college and preparation with discipline and regular revision.

Your date of birth is 24th February 2006, and you will complete graduation in July 2028. For the CDS exam, the maximum number of attempts depends on your age limit and category, but generally, candidates have around 4 to 6 attempts before reaching the age limit.

For CDS 2 2025, with a date of birth of 6th October 2001, you are eligible for both IMA and OTA. The age limits for IMA are 19-24 years and for OTA are 19-25 years as of 1st January 2025, making you eligible for both academies.
