Chemistry Placement Exam

The Chemistry Placement Exam is offered multiple times a year to Ohio University students to help place them into the correct level of chemistry courses. The exam is administered by the Chemistry & Biochemistry Department.

The requisite for CHEM 1510 Fundamentals of Chemistry I can be met by either of the following ways:

  1. C- or better in CHEM 1500 (Concepts in Chemistry) AND (Math placement 2 or MATH 1200 or higher) CHEM 1500 (Concepts in Chemistry) is designed to prepare students for CHEM 1510.  The requisite for CHEM 1500 is Math Placement 2.  Students with Math Placement 1 are allowed to take CHEM 1500 concurrently with MATH 1200 (College Algebra).
  2. 55% or higher on the ALEKS Initial Assessment AND (Math placement 2 or MATH 1200 or higher) ALEKS is an artificial intelligence based teaching tool and is available online.  You should plan to set aside 1-2 hours for the assessment.  A score of 55% along with a Math Placement 2 or higher math level (or course equivalent) will allow you to register for CHEM 1510.

Students who do not meet the requisite via the ALEKS assessment must take CHEM 1500.

The topics for the questions include, but are not limited to:

  • Algebraic manipulation
  • Calculations using scientific notation and proper number of significant figures
  • Interpretation of graphs
  • Balancing chemical equations
  • States of matter
  • Periodic table interpretation and significance
  • Names and formulas for compounds
  • Stoichiometric calculations
  • Gas laws
  • Molecular geometry
