​Chemistry Diagnostic Exam & Requirements

Most undergraduate engineering degrees require a minimum sequence of chemistry courses. Normally, only biomedical and chemical engineering students take chemistry during their first year, and students majoring in other areas of engineering take one semester of chemistry during their sophomore year. If you are not sure what area of engineering you want to pursue, but are considering biomedical or chemical engineering, you should take chemistry during your first semester.

  • CHEM (L07) 111A: General Chemistry I (3 units) - offered only FALL semester
  • CHEM (L07) 151: General Chemistry Laboratory I (2 units) - offered only FALL
  • CHEM (L07) 112A: General Chemistry II (3 units) - offered only SPRING semester

Chemistry Online Diagnostic Exam Details

Dear First-Year Student,

All first-year students registering for General Chemistry I (Chemistry 111A) in the fall are expected to take the online chemistry diagnostic exam between June 11, 2018 and August 10, 2018. Before you take the exam you should review the online tutorial, practice problems and practice quiz questions. The objectives of the online diagnostic exam and tutorial are:

  • To provide a means and motivation for you to review pre-requisite material that is needed to be successful in Chemistry 111A but which is not explicitly covered in the Chem 111A lectures.
  • To help fill in gaps in your knowledge base (via the online tutorials) and to provide a means of identifying areas that need further work (via the online diagnostic exam).
  • To identify students who may require supplementary resources at WU such as specific topic-based review workshops and extended recitation sections. Recommendations regarding extended recitations will be given to you by your academic advisor when you meet him or her in late August.
  • To introduce interested students to real-life applications and cutting-edge research that takes place in the Department of Chemistry through Advanced Application tutorials.

The tutorial, practice problems and quizzes, and the diagnostic exam are accessible at: You will need your six-digit WU student ID number to access this website, but no password is required. If you have questions about your student ID number or any problems logging onto the website please, please contact Dr. Jia Luo via e-mail ( or phone (314-935-4163). Contact by email is preferred.

The tutorial website contains Exam Instructions, Frequently Asked Questions and a Hints page. We appreciate your comments, so please feel free to submit your feedback via the "Feedback/Comments" link on the tutorial page.

Chemistry Diagnostic Exam

Students who plan to take chemistry during the first semester should use their WUSTL student ID numbers to complete the chemistry diagnostic exam between June 11, 2018 and August 10, 2018. Tutorials, practice problems, quizzes and exam are accessible online:
This is a diagnostic exam, so you cannot fail. The results of this exam do not impact your ability to register for Chemistry 111A. The two-hour exam consists of 28 multiple-choice test items covering basic material taught in high school general chemistry courses.

Physics Preparation

Chemistry at WU requires a solid preparation in Physics. If you did not take a calculus based Physics course in your junior or senior year of high school, please discuss your chemistry enrollment with your four year advisor.

Note for students planning a second major or minor in chemistry

Engineering students considering a second major or minor in chemistry in the College of Arts & Sciences should not use AP credit for proficiency. All Chemistry credit for a second major or minor must be taken at Washington University. The Department of Chemistry does not honor the AP score as proficiency credit.

Note for Premedical Students

There are some medical schools that do not accept AP or any other placement credit. There are also medical schools that insist on upper-level course work in the same discipline for students who have received placement credit. Students anticipating a career in medicine who take Chemistry 111A and 112A as freshmen, even if they have an AP score of "5," will probably increase their options on schools because they will not be limited by the non-acceptance of AP credit. If you have further questions regarding this, please e-mail Ron Laue, the Health Professions Advisor for the School of Engineering & Applied Science:
