Preparation Strategy for CDS II 2026

A strategic approach is essential given the high volume of candidates and the negative marking system.

  • Master the Basics: For Mathematics, revisit NCERT textbooks to solidify your fundamentals. For English, focus on objective grammar and frequent reading of editorials.
  • Current Affairs: Stay updated with national and international events for at least the 6-8 months preceding the exam. Pay special attention to defence-related news and technology.
  • Time Management: Since you have 120 minutes per paper, speed and accuracy are vital. Practicing with full-length mocks is the only way to master this.
  • Subject Integration: If you are also preparing for other defence exams, ensure your study plan covers overlapping topics. For instance, resources like the Defence: NDA / CDS / AFCAT pack can help streamline your preparation across multiple entries.
