Chemistry in the NDA Paper
Chemistry questions test definitions, common reactions, applications of metals/non-metals/salts, acid-base concepts, and recall of compounds. Class 9-10 covers the bulk; Class 11 adds atomic structure depth.
18-Topic Syllabus
Cluster A — Atomic Structure & Bonding (3)
Cluster B — Matter & Changes (2)
Cluster C — Acid-Base & Salt (4)
Cluster D — Reactions (4)
Cluster E — Materials & Applications (5)
6-Week Plan
- Week 1: Atomic structure, isotopes, bonding.

How many Chemistry questions in NDA?
Roughly 6-10 per Paper II GAT. ~24-40 marks.
Is NCERT enough?
NCERT Class 9-11 covers ~85-90% of NDA Chemistry. PYQ practice fills the rest.
Are organic chemistry questions hard in NDA?
No — NDA tests basic hydrocarbons, fuel chemistry, common polymers. Class 10 NCERT level is enough.
