Grade Calculations

The MBS school year is divided into quarters. Student Grade Reports are sent to the parents four times a year.  The fourth quarter report card is mailed to the student  and is the final copy of the student’s grades for the year.  Progress Reports and a current transcript can be viewed at any time through the iNow Parent Home Portal.


1st Nine Weeks – 40%                                                                           3rd Nine Weeks – 40%

2nd Nine Weeks – 40%                                                                          4th Nine Weeks – 40%

Semester Exam – 20%                                                                            Semester Exam – 20%

MBS calculates two GPAs.  The unweighted GPA includes all courses a student has completed.  The weighted GPA includes only academic courses and gives additional points for advanced or AP classes.  Academic courses are listed below.  GPAs are available at the end of each semester;  final GPA is computed at the end of 8 semesters. Both the weighted and unweighted GPAs are included on a student’s transcript.

The courses listed below will be used to compute weighted grade point average (GPA).  On the weighted 100-point numerical system, ten points are added to final grades earned in AP classes; five points are added to final grades earned in advanced classes.  (Example:  English AP=90.  This grade of 90 will appear on the transcript as the raw and unweighted grade.  The computer will add ten points to the grade so that it will be computed as 100. English Advanced=90.  The computer will add five points so that it will be computed as 95, but once again, the raw, unweighted grade of 90 will appear on the transcript).  An extra point will be added on the 4.0 scale for AP courses, and 0.5 point will be added on the 4.0 scale for advanced courses for college application purposes.


A=5.0 (AP)

B=4.0 (AP)

C=3.0 (AP)

D=1.0 (AP)

A=4.5 (Adv)

B=3.5 (Adv)

C=2.5 (Adv)

D=1.0 (Adv)

A=4.0 (Reg)

B=3.0 (Reg)

C=2.0 (Reg)

D=1.0 (Reg)


Students who plan to attend highly selective or competitive colleges are encouraged to challenge themselves with a rigorous curriculum consisting of Advanced and AP courses according to their ability.  Completion of these courses is a significant factor in the college admissions decision.

If you have any further questions regarding GPA, please see a counselor.
