If you have the right permission, click on "Edit Course Types" on the Configure page. On this page, you can add, edit, and deactivate different types of courses in your school. Differentiating courses like this can be helpful when analyzing student course grades and results on the Analysis page.
For example, if your school has honors courses, you can add that course type by selecting the green button at the top right-hand corner of the page. You can also choose to hide the suffix of the course type throughout the site, such as on report cards and slips. As always, don't forget to save!
