2019 Chem 13 News and Avogadro Exams

Do you have a 75-minute period to challenge your students chemically? Give them the experience of writing the Chem 13 News Exam or Avogadro Exam! The Chem 13 News Exam will be written on Thursday, May 9, 2019, and is designed for senior students in their second high school chemistry course. The Avogadro Exam will be written on Thursday, May 16, 2019, and is designed for students in their first high school chemistry course. 
All students will be writing the Chem 13 News and the Avogadro Exams live online. The exam format will be the same as in previous years, with 40 multiple choice questions. Having students write online allows us to have results back quickly, avoid shipping fees and have more statistical exam feedback for teachers to explore. Using our online platform, teachers will be able to see how their students did on the exam and on each question relative to all students writing the exam.

The deadline for ordering these exams is Friday, April 19, 2019. The cost to write the contest is $3.50 per student.
