About CDS Elementary Mathematics PYQs
These are the official questions asked in the CDS (Combined Defence Services) examination conducted by UPSC, covering 2016–2026. UPSC conducts the CDS exam twice every year — CDS I (April) and CDS II (September). This bank includes both papers of each year.
Chapter-wise PYQ practice is the fastest way to master CDS Elementary Mathematics: the exam repeats topics, question styles and difficulty patterns consistently. Working through past questions topic by topic shows you exactly what UPSC asks — and how often.
