- Referencing Phase: Use 'Mathematics for NDA & NA' by R.S. Aggarwal and 'Pathfinder for NDA' by Arihant. These are the gold standards for self-study.
- GAT Mastery: Use 'Word Power Made Easy' for vocabulary and any standard Geography/History NCERTs for the GAT section.
- Practice Phase: Consistency is key. You should analyze previous year papers for Defence on Exam Bhai to understand the repeating trends in questions.
