List all the students’ ids and their GPA The GPA is calculated by summing up the grade of each course multiplied the number of credits for the course and then dividing the result by the total number of credits the student has taken.

[@priangshumukherjee]

Your hard work will pay up

[@GauravSharma-ze4cu]

I think there is some mistake in part c if you join the tables then you also have to mention the join condition. which is ( student.rollno = college.rollno and teachers.teacherid = college.teacherid ) i guess this condition is ok O_o'

Sir in c) question college relation is not used but you have joined the college by join whether it is mandatory to join all the relation or not

[@Farbistaa]

It’s because of common attribute. Teacher ID is common on Teacher Table as well as on College students Table.
