What This Document Is
This document is a practice test for CHEM 121, General Chemistry I, at Western Washington University. It’s designed to assess your understanding of foundational chemistry concepts typically covered in the early stages of the course. The test focuses on core principles and problem-solving skills essential for success in general chemistry. Expect questions that require you to demonstrate knowledge of chemical nomenclature, unit conversions, and basic calculations.
Why This Document Matters
This resource is invaluable for students preparing for their first exam in CHEM 121. It’s particularly helpful for identifying knowledge gaps and strengthening areas where you may need further review. Utilizing this test under timed conditions can simulate the actual exam environment, helping you build confidence and manage your time effectively.

Students who proactively use practice tests often perform better on graded assessments.
Common Limitations or Challenges
This test represents a single assessment and doesn’t encompass *every* possible topic covered in CHEM 121. It’s crucial to remember that this is a snapshot of potential exam questions, and the actual exam may vary in format and content emphasis. This resource does not provide detailed explanations or step-by-step solutions; it’s designed to test your existing knowledge, not teach you new material. It also doesn’t replace the need for a thorough understanding of the course syllabus and professor’s expectations.
