**What This Document Is**
This is a practice exam for CHEM 105, General Chemistry, at the University of Southern California.

It’s formatted as a full exam, including space for student identification and an academic integrity pledge. The document assesses understanding of core chemistry principles through a variety of question types.
**Why This Document Matters**
This resource is invaluable for any USC student currently enrolled in CHEM 105 who wants to proactively assess their understanding of the course material. Working through practice exams under timed conditions is one of the most effective study methods. This particular practice exam allows you to familiarize yourself with the style of questions Dr. Parr typically asks, the scope of topics covered on Exam 2, and the overall exam format. It’s best used *after* you’ve completed the relevant readings and problem sets, as a way to solidify your knowledge and identify areas needing further review.
**Common Limitations or Challenges**
While this practice exam is a strong indicator of the types of questions you might encounter, it’s important to remember that exam content varies. This is a past exam, and the specific topics emphasized or the exact wording of questions may differ on future assessments. This document *does not* include detailed explanations or worked-out solutions; it’s designed to test your existing knowledge, not teach you new concepts. Access to the key with solutions is required to fully benefit from this practice exam.
