How to Improve Maths and GK for the NDA Written Exam Quickly

When the NDA written exam is close, you don't need more study — you need smarter study. The two areas with the fastest improvement curve are Mathematics and the General Knowledge portion of the GAT. Here's a focused plan to lift both quickly without burning out.

Know the weightage before you study

The written exam is 900 marks: Maths (300) and GAT (600), where GAT = English + General Knowledge. Because Maths is purely objective and GK is fact-based, both are high-yield if you target the right topics. Random studying wastes your scarcest resource — time.

Maths: attack the high-weightage chapters first

Don't study Maths alphabetically — study it by return on investment. Prioritise:

• Trigonometry — heights & distances, identities, inverse functions.
• Calculus — limits, differentiation, integration, applications.
• Matrices & Determinants — quick, formula-driven marks.
• Probability & Statistics — high-frequency, learnable patterns.
• Complex Numbers, Quadratic Equations, 2D/3D Geometry.

The method that works fastest: learn the concept → solve previous-year questions → time yourself. Speed comes from pattern recognition, and patterns come from repetition. Use our chapter-wise NDA Maths study material to revise formulas and drill PYQs efficiently.

GK: cover the static syllabus by linking, not cramming

NDA GK spans Physics, Chemistry, General Science, History, Geography and Polity. Trying to memorise it cold is exhausting. Instead, study it as connected subjects:

• History — focus on modern India and the freedom struggle: our History notes.
• Geography — Indian physical & economic geography, maps: our Geography notes.
• Polity — Constitution basics, Fundamental Rights, Parliament: our Polity notes.
• General Science — everyday Physics and Chemistry concepts.

Current affairs: the easy marks people skip

A reliable slice of GAT comes from current events — defence, awards, summits, sports, science. The trick is little-and-often: spend 15–20 minutes daily rather than cramming a year in a weekend. Our daily NDA current affairs are written exam-style, so revision doubles as practice.

A sample 4-week rapid-improvement routine

• Morning (90 min): One Maths chapter — concept + 20–25 PYQs.
• Afternoon (60 min): One GK subject + 30 objective questions.
• Evening (30 min): Current affairs + English (vocab/grammar/comprehension).
• Weekend: One full-length mock test + detailed mistake analysis.

Three rules that accelerate everything

1. Previous-year papers are king — they reveal exactly what's asked and how.
2. Maintain an error log — your mistakes are your personalised syllabus.
3. Revise weekly — unrevised topics quietly disappear before exam day.

Follow this for a few weeks and both your Maths accuracy and GK recall will climb fast. For a guided, time-bound push, see our NDA crash course guide and the latest batches.
