What This Document Is
This document is a past examination for CS 225 Data Structures and Software Principles, offered at the University of Illinois at Urbana-Champaign. Specifically, it represents the first midterm exam administered in Fall 2012. It’s designed to assess understanding of fundamental concepts covered early in the course. The exam format includes multiple-choice questions, testing both conceptual knowledge and the ability to reason about code behavior.
Why This Document Matters
This resource is invaluable for students currently enrolled in, or preparing to take, a similar data structures course. It provides a realistic assessment of the types of questions and the level of difficulty you can expect on an exam. Working through past exams is a proven strategy for identifying knowledge gaps and refining problem-solving skills. It’s particularly useful for self-assessment and practice under timed conditions, helping to build confidence before a high-stakes evaluation. Accessing the full exam allows for a comprehensive review of core principles.
