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.
