Gradebook is where all your grading & assignments marking are stored, and it will be automatically calculated based on your subject criteria, which your school system administrator has preconfigured.
You can easily create any graded or/and ungraded Assignment by clicking "Create Assignment" on the top right of the page.
The created Assignment will be displayed in the grade book according to each assignment grading category and will be automatically calculated for each student's total grade per quarter or term using the grading category percentage weight; it may also show the grading scale if your school preconfigures it.
The assignment is separately calculated by converting each student assignment grade to a percentage, then getting the average percent of each grading category solely and weighting it to the grading category total weight.
Gradebook can be accessed by your supervisor or head of the department in readonly mode, also when the current quarter or term ended, the gradebook assignments cannot be modified any longer by the teacher.
If the school has the gradebook enabled for students or/and parents it will be available for them after your assignment's due date.
