EM Tests (Credit by Examination)

If you are a current Ohio State undergraduate and interested in testing out of a course in Chemistry, you must meet with one of the Chemistry advisors to determine your eligibility for the exam and to obtain a testing referral. A syllabus for the course is also available from the Chemistry advisors.

EM credit is not available for Chemistry 1100 or for Chemistry courses at the 2000 level and above. All exams are taken in the Ohio State University Testing Center in the Student Academic Services Building (614­-292-­2241; 585 Student Academic Services Building, 281 West Lane Ave).

Who should you contact first about taking an EM Test in Chemistry?

Please call our Undergraduate Office at (614) 292­1204 to make an appointment to meet with:

  • Student last name A­H: Dr. Shuh­Kuen (Mike) Chang (chang.479@osu.edu)
  • Student last name I­Z: Mrs. Mary Bailey (bailey.3@osu.edu )

What are the criteria required to qualify for taking EM Tests?

  • The prerequisite for the course
  • A comparable college level chemistry lecture and lab experience
  • Cannot have a previous mark in the course (including a grade of W or R for audit).

What are the courses in which EM Tests are available?

  • 1110 Elementary Chemistry (5): 2.5­hour exam

    Introductory chemistry for non­science majors, including: dimensional analysis, atomic structure, bonding, chemical reactions, states of matter, solutions, chemical equilibrium, acids and bases, and topics in organic and biological chemistry. Students must show proof of placement in Math 1116 or higher. Not open to students with credit for Chemistry 1210, 1250, 1610, or 1910H.

  • 1210 General Chemistry I (5): 2­hour exam

    First course for science majors covering: dimensional analysis, atomic structure, the mole, stoichiometry, chemical reactions, thermochemistry, electron configuration, bonding, molecular structure, gases, and solids. Prerequisite: high school chemistry or equivalent, and proof of placement into Math 1150 or higher is required. Not open to students with credit for Chemistry 1250, 1610, or 1910H.

  • 1215 General Chemistry Bridge (2): 1­hour 45­min exam

    A bridge course for students with credit for CHEM 121 who want to move on to CHEM 1220. Topics include: gases, liquids and intermolecular forces, and solids. Prerequisite: 121, 161, or 201H; and proof of placement into Math 1150 (150) or higher. Not open to students with credit for CHEM 1210, 122, or 123.

  • 1220 General Chemistry II (5): 2.5­hour exam

    A continuation of 1210 for science majors covering: liquids and intermolecular forces, solutions, kinetics, chemical equilibrium, solubility and ionic equilibria, qualitative analysis, thermodynamics, electrochemistry, descriptive chemistry, coordination compounds, and nuclear chemistry. Prerequisites: 1210, 1250, 1610, or 1910H, and proof of placement in Math 1150 or higher. Not open to students with credit for Chemistry 1620 or 1920H.

  • 1250 General Chemistry for Engineers (4): 2.5­hour exam

    First course for engineering majors covering: dimensional analysis, atomic and molecular structure, the mole, stoichiometry, chemical reactions, states of matter, solutions, kinetics, equilibrium, acids and bases, thermodynamics, and electrochemistry. Prerequisite: One unit of high school chemistry and placement into Math 1150 or higher. Not open to students with credit for Chemistry 1210, 1610, or 1910H.

Things you should know about taking an EM Test in Chemistry:

  • The test is similar to a final exam in the course, which is composed of 40­50 multiple choice questions, including laboratory questions.
  • A periodic table will be provided if appropriate.
  • On all of the Chemistry exams, a score of 65% or higher is required to receive credit.
  • You have only one chance to take the test.
  • You must bring your ID and a testing referral, which can be obtained by meeting with an advisor in Room 110 Celeste Lab, 100 W. 18th Ave.
  • In most cases, the Office of Testing will grade the test right after you take it and tell you the results immediately.
  • There is an administration fee of $60.00 for each EM Test, payable to Ohio State during the online registration process.
  • Only non­programmable calculators may be used during the EM Tests in the Chemistry series. Calculators may not be shared. Please see the calculator guide at https://undergrad-ed.chemistry.ohio-state.edu/calculators/.
  • Students with disabilities should contact the Ohio State Office for Disability Services, (614) 292­3307, to make alternate arrangements for taking the EM Tests.
