Bilkent University's official grading system uses letter grades with pluses and minuses. Passing grades range from A+ to D; F, FX is failing. The quality-point equivalents of the grades are:

The grades and their quality-point equivalents are:

Other grades used are S (Satisfactory), U (Unsatisfactory), I (Incomplete), P (In Progress), T (Transfer), and W (Withdraw). These grades do not have quality-point equivalents.

S : accorded to students who are successful in non-credit courses.

U : accorded to students who are unsuccessful in non-credit courses.

I : accorded to students who, although otherwise successful, have failed to complete the required assignments for a course due to illness or some other valid reason. Proof of illness or other reason for non-completion must be submitted to the department chair within three days of the date of the final exam. A student receiving an incomplete grade for any course must make up for the deficiencies within 15 days after the final exam in order to obtain a grade. Otherwise, the grade I automatically becomes FX. At the discretion of the department chair, the period specified above may be extended until the beginning of the following semester.

P : progress.

T : reflects approved transferred courses from other universities or from an exchange program. A student with a grade of T is exempted from an equivalent number of credits on the condition that the courses are accepted by the department on the recommendation of the department chair and with the approval of the board of the faculty/school. This grade may provide an exemption for a particular course at the program.

W : student has withdrawn from the course before the end of the semester.

A student with extraordinary performance in a course may be granted an A+ grade. However, the number of A+ grades in a given course is limited based on class size: If the class size is less than 25 students, no A+ grades may be given; if the class size is between 25 and 74 students, only one A+ grade may be given; if the class size is between 75 and 124 students, two A+ grades may be given; if the class size is between 125 and 174 students, three A+ grades may be given; if the class size is between 175 and 225 students, four A+ grades may be given; if the class size is more than 225 students, five A+ grades may be given. (The letter grade A+ was instituted beginning with the 2010-2011 academic year.)

An undergraduate student who receives a grade of C or higher in a course (or S in a non-credit course) is considered to have satisfactorily completed that course.

A student who receives a grade of C-, D+, or D in a course can only be considered to have completed that course if his/her Cumulative Grade Point Average (CGPA) is 2.00 or higher.

A student receiving either F, FX, FZ, or U in a course is considered to be unsuccessful in that course.

A graduate student is considered to have satisfactorily completed a course when he/she receives a grade of C or higher in an M.A or M.S. program, and a B or higher in a Ph.D. program. A graduate student receiving any other grade (except for S, T, P, or I) is considered to have been unsuccessful in completing that course.


Grade Point Average (GPA) and Cumulative Grade Point Average (CGPA)

A student's academic performance is determined at the end of each semester by computing an average of the grades he/she has received during that semester. For each course, the grade point equivalent of the letter grade received by the student is multiplied by the credit units for that course; the sum of these products is then divided by the total credit units taken in that semester to yield the Grade Point Average (GPA) for that semester. The Cumulative Grade Point Average (CGPA) is calculated by multiplying the grade point equivalent of the letter grade by the credit units for each course and then dividing the total sum by the total credit units taken in the program.
