i want to create a system of mark insertion. the class does English, French and Mathematics. it has a login system. when a French teacher logs in, then only the subject French should appear. Administrator can view and modify the content of all subjects. The system should generate the grade, remarks, average, pass or fail. It then generates a report card for each student of the class, showing the subjects and marks achieved. Explain step by step what to do and how to do it.
