Example Student table: Update Query in VBScript



''================================================================= 
            Create a new table in MS Access called Student and perform given task.

        Student Table Structure
           1.       RollNo

Write a script to perform below task:
1.       Function to calculate Avg Marks of all subjects and update in Avg Marks column.(for all subject)
2.       Function to calculate total marks and update in the total column.
