- CHM is the course designator—in this case, it’s short for Chemistry; 220 is the course number and indicates the level of the course. There are 100-, 200-, 300- and 400-level courses; courses for first-year students are normally numbered at the 100-level, second year courses are normally numbered at the 200-level.

- 1 means taught on the St. George Campus (3 means Scarborough Campus, and 5 means Mississauga Campus).
- Prerequisites are the courses you need to take before you are qualified to take this one. For CHM220H1, you need 1.0 course credit in Chemistry (CHM135H1 and CHM136H1 or CHM151Y1) and1.0 course credit in Mathematics (MAT135H1 + MAT136H1 or MAT137Y1 or MAT157Y1).
- Co-requisites are courses you must take at the same time as this course. For instance, it is recommended that you take either MAT235Y1 or MAT237Y1 at the same time that you take CHM220H1.
- Exclusions are courses similar enough to this course that you may not receive degree credit for both. If you have completed in the past, or are concurrently enrolled in, any of the listed exclusions, you are not allowed to take this course as well. In this example, you may not take CHM220H1 if you have passed or are concurrently taking any of CHM225Y1, CHM222H1, CHMB20H3, JCP221H5, or CHM221H5.
- The Distribution Requirement Status of the course applies to students who began degree studies prior to September 2010. CHM220H1 is a science course for Distribution Requirement purposes.
- Breadth Requirement applies to students who began degree studies in September 2010 or after. CHM220H1 is a category 5 course (The Physical and Mathematical Universes).
