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'

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.
