SECTION C: CASE STUDY (40 MARKS)

Develop a Student Grade Calculator App that acts as a digital gradebook for teachers. The app should allow teachers to:•Enter three student details (name, ID, course) and three subjects with marks and credit hours.

•Automatically convert marks to grade points, calculate GPA using the formula:

GPA = Σ(grade points × credit hours) / total credit hoursand classify students into fixed grade categories (A to F).

•Store all data in a well-structured SQLite database with proper relationships between students and subjects.

•View student details and grades using AlertDialogs with search functionality by name or ID.

•Generate class statistics via AlertDialogs: total students, average GPA, highest/lowest GPA, and grade distribution.

•Use a hardcoded grading scale (A: 3.7–4.0, B+: 3.3–3.69, etc.) (40 Marks)
