Grades, Notations, and Symbols

Grade definitions are published in the MIT Course Catalog.

Below is additional information on certain grades, notations and symbols that, unless otherwise noted, appear on both the internal grade report and the transcript.

I Incomplete. An I is not calculated in the grade point average. When the work is completed, the final grade appears next to the I (example: I/B)
O Absent. This grade is equivalent to the grade of F and is calculated in the grade point average with the same weight as F. Before a final grade can be awarded, the O must be converted to an OX.
OX Absence excused. An OX is not included in the calculation of the grade point average. When the work is completed, the final grade appears next to the OX on the internal grade report. On the transcript the final grade replaces the OX.
J, U These notations are for work not yet completed in thesis, UROP, special topics, or at plant registration. When the final grade is submitted, it appears by itself in the term in which the subject was completed and appears in prior terms next to a J or U (example: J/A or U/A).
S This notation is for transfer credit, work done elsewhere. It is not included in the calculation of the grade point average.
T This notation appears only on the internal grade report, not on the transcript. The subject and final grade appear on the transcript in the term in which the subject was completed.
URN This notation is for UROP taken for pay or as a volunteer. It appears as 1 unit of non-degree credit.
** This symbol indicates the grade is missing; the instructor has not submitted a grade. It appears as MG on the transcript.
& This symbol indicates a grade for an Advanced Standing Exam. Grades for advanced standing exams are not included in the calculation of the grade point average.
# This symbol indicates a grade for a ROTC subject. A ROTC subject is not included in degree credit and the grade is not included in the calculation of the grade point average.
@ This symbol indicates a subject taken on Junior-Senior P/D/F. It appears only on the internal grade report, not on the transcript.
