What does the letter I mean on your college Transcript mean?

On a college transcript, the letter "I" typically means Incomplete. This indicates that a student has not completed all the required work for a course by the official deadline, but there's an agreement or possibility to finish the remaining work within a specified timeframe. The grade will change once the incomplete work is submitted and graded. If the work isn't completed within the allotted time, the "I" may be changed to a failing grade (like an F) or another failing grade designation used by that institution.
