We recommend keeping a close watch on the UPSC website to avoid missing the specific application windows for NDA I and II.

Preparation Strategy

To succeed, we at Exam Bhai suggest a multi-layered approach:

1. Foundational Phase: Start with NCERT books (Class 11 & 12). They are the gold standard for the written paper.
2. Specialized Books: Supplement NCERTs with Mathematics for NDA/NA by R.S. Aggarwal and Objective General English by S.P. Bakshi.
3. Practice: Regularly practice free mock tests for Defence on Exam Bhai to simulate real exam pressure.
4. Current Affairs: Read a national newspaper like The Hindu or The Indian Express daily to tackle the current events section of GAT.

Cut-Off Trends

Based on data from the UPSC official result portal, the cut-off fluctuates based on paper difficulty. Historically, the written cut-off ranges between 290 and 360 out of 900. To be in a safe zone, we advise aiming for 380+ marks in your mock assessments to account for negative marking and yearly variations.
