    Unanswered: ER diagram help

    For this scenario, could you help me to draw ER-Diagram.

    In a university system, There are various exam types called Quizes, Practicals, End semester exams and mid semester exams per each subject.

    Marks are allocated differently for each exam.

    Grade should also be calculated in each subject with Quizes, Practicals, End sem exam and mid sem exam per each child.
