CHEM 1P91 / 1P92 Admission Test

Students who do not have a minimum of 70% in Ontario grade 12 chemistry or equivalent may write an assessment test in order to see if their background in chemistry is sufficiently strong to succeed in CHEM 1P91/1P92 . The test takes approximately 90 minutes to write. There is no cost for writing the test. Students must achieve 70% or higher on the assessment test in order to be admitted into CHEM 1P91/1P92 , if they do not have a minimum of 70% in Ontario grade 12 chemistry.

Test Information

Assessment Test Schedule (2020)  UPDATED April 27,2020

  • The option of completing a competency test for entry into CHEM 1P91/1P92, for those students who do not meet the prerequisite 70% minimum in Ontario grade 12 chemistry (SCH4U) or equivalent, is not available at present for fall 2020.  Information will be posted here, should this situation change.

The questions given in the sections below are representative of the kinds of questions that appear on the assessment test to determine if students have sufficient Chemistry to succeed in CHEM 1P91/1P92 . Actual questions on the exam each year will vary.

The best way to study for this exam is to use your Chemistry textbook or a Chemistry Study Guide and work the problems/answer questions at the end of each chapter in the textbook you have chosen. You cannot learn how to do chemistry by looking at the answers someone else has provided!

Pay special attention to definitions and concepts. If you don’t know what the words mean, you can’t work the problem!

Questions on the Equivalency Exam are not equally weighted. Some are more complex than others, and the marks on each question reflect this.
