Indian Coast Guard Assistant Commandant – CGCAT 2025 Syllabus & Exam Pattern

Selection Process Overview

  • Indian Coast Guard Assistant Commandant (ICG AC) is a Group-A Gazetted Officer post; selection is regarded as highly prestigious within the Indian armed forces.
  • 5 sequential stages of selection:
    • CGCAT (Coast Guard Common Admission Test) – Computer-based, objective-type, 400400 marks.
    • PSB (Preliminary Selection Board) – Officers’ interaction and document verification.
    • FSB (Final Selection Board) – Comprehensive interview, psych tests, and group tasks.
    • Medical Examination – Conducted at authorised military hospitals; candidates must meet prescribed standards.
    • Induction – Successful candidates join as trainee Assistant Commandants.
  • Clearing CGCAT is compulsory for progression; consequently, most preparation strategies focus on mastering its syllabus and understanding the pattern.

CGCAT Exam Pattern (2025 Cycle)

  • Mode: Online (computer-based).
  • Total Questions: 100 (objective, multiple-choice).
  • Total Marks: 400400 (\Rightarrow) each question carries 44 marks; negative marking (if any) to be confirmed from the official notice.
  • Composite Duration: 22 hours (120 minutes) – no sectional time limits.
  • Section-wise breakup (25 questions each):
    1. English
    2. Reasoning & Numerical Ability
    3. General Science & Mathematical Aptitude
    4. General Knowledge
  • Scoring tip: target (\ge 60\%) raw score (i.e.

  • Practise at least 55 full-length CGCAT mocks; analyse accuracy vs speed.
  • Maintain a formula sheet; revise thermodynamics and mechanics equations daily.
  • For English, read editorials; record new words in a personal lexicon.
  • Use Venn diagrams and family charts to accelerate blood-relation questions.
  • In PP/DT, adopt the “WHO-WHAT-WHY-OUTCOME” framework while crafting the story.

  • Precise communication (tested via English) is vital for joint maritime operations to avoid strategic misinterpretations.
  • Logical reasoning ensures quick, bias-free decisions during search-and-rescue missions.
  • Scientific literacy underpins effective use of navigation systems, radar, and chemical handling on ships.
  • Physical & mental robustness (tested later) complete the holistic officership model that begins with CGCAT’s academic filter.
