# The Qualifying Exam Syllabus

The questions on the Qualifying Exam (Quals) aim to test your ability to solve concrete problems by identifying and applying important theorems. They should not require great ingenuity. In any given year, the exam may not cover every topic on the syllabus, but it should cover a broadly representative set of Quals topics and over time all Quals topics should be examined.

The Qualifying Exam syllabus is divided into six areas. In each case, we suggest a book to more carefully define the syllabus. The examiners are asked to limit their questions to major Quals topics covered in these books. We have tried to choose books we think are good. However, there are many good books and others might better suit your needs.
