## What you need to know

Some key points to remember:

• The following are not included in the calculation:
• Subjects with a grade of P, S, URN, SA, T
• Subjects, if not completed, with a grade of I, OX, J, U
• ROTC subjects
• Since P grades are not used in calculating GPA, first-year students will not have a GPA until the spring semester concludes.
• A repeated subject counts in your GPA each time you take it.

## How to calculate your GPA

Grades used in the calculation if your GPA are weighted as follows: A=5, B=4, C=3, D=2, F=0, O=0.

• To calculate your GPA, total all the units of A-level work and multiply this number by 5. Then, total all units of B-level work and multiply by 4 and so on.
• When you complete an ongoing subject, other than thesis, take the sum of the units of J grade received in prior terms and apply the final grade to the total.
• Add the results and divide by the total number of units.
• Round to the first place after the decimal point. If the hundredth place is 5 or above, the tenth place rounds up (4.75=4.8). If the hundredth place is 4 or below, the tenth place rounds down (4.74=4.7).
• For a master’s level thesis, a maximum of 24 units is used in your GPA calculation; doctoral level thesis units (which receive the grade of SA) are not included.

## GPA conversions

• Three MIT credit units are equal to one semester hour.
• To convert your GPA to a 4.0 scale, substitute the following values in the calculation above: A=4, B=3, C=2, D=1, F=0, O=0.
• Conversion to a 4.0 scale is not valid for students who attended MIT prior to 1970.
