: Focuses on counting strategies and essay-type proofs to develop significant problem-solving experience. Quadratic Diophantine Equations
: Clusters problems by topic into self-contained sections, each starting with an essay on basic facts. Complex Numbers from A to... Z
: Targeted at higher-level undergraduates, it covers advanced topics in algebra, geometry, and real analysis. A Path to Combinatorics for Undergraduates
This is the perfect starting point for students transitioning from school math to competition math. It covers the basic segments of the Olympiad curriculum, providing a bridge between standard concepts and complex problem-solving. 2.

A highly structured workbook that takes students from high school algebra to the advanced techniques required for the USAMO.
Co-authored with Bogdan Enescu, this book targets the transition from regional competitions to national Olympiads, focusing heavily on algebraic structures.

Try the problems yourself before looking at the solutions.
Accessing a PDF is only the first step. To get the most out of Titu Andreescu's work:
Perhaps his most famous work, this book is a staple for advanced students. It is not a textbook in the traditional sense but a collection of problems organized by theme (Number Theory, Geometry, Algebra, Combinatorics). It is renowned for its elegant solutions and the "Synthesis" sections which link concepts together.
