This is what I tried.

Answer 1

You can try this code. It must work perfectly :

 select s.student_name
    from student s
    join mark m
    on s.student_id=m.student_id
    join subject s1
    on s1.subject_id=m.subject_id
    where m.value=(select max(m1.value) from mark m1 
                     join subject s2
                     on s2.subject_id=m1.subject_id
                     where lower(s2.subject_name)='software engineering'
    group by s2.subject_id)
    group by s.student_name
    order by s.student_name;
