When designating a course as "In Progress", in both the course description and in the grade field of your transcript, the abbreviation IP is used to show that a course is "In Progress" (meaning the student is currently taking the course, but has not yet received a grade for the course) as shown below.
You may not want to have this abbreviation shown twice. You can remove IP from being shown to the right of the course by following the instructions below.
Log in to your account, then click on "Settings" at the very top of the page (this is the Settings tab to the right of the Transcripts tab).
Then click on "Course Statuses".
In "Course Statuses", clear the "Abbrev" field for the "In Progress" course type, and click the "Save Changes" button.
This will remove the IP abbreviation from the course column (please be aware that this will remove the abbreviation across all of your transcripts).
