Hi,
Try this query

SQL

SELECT SU.SubjectCode, SU.SubjectName,
 CASE WHEN SU.SubjectCode='Subject1'
         THEN (SELECT Distinct Subject1 FROM StudentGrade)
 CASE WHEN SU.SubjectCode='Subject2'
         THEN (SELECT Distinct Subject2 FROM StudentGrade)
 CASE WHEN SU.SubjectCode='Subject3'
      THEN (SELECT Distinct Subject3 FROM StudentGrade)
 CASE WHEN SU.SubjectCode='Subject4'
      THEN (SELECT Distinct Subject4 FROM StudentGrade)
 ELSE NULL END AS 'Grade',
 CASE WHEN Grade IN ('a','b') THEN 'Pass' ELSE 'Fail' END AS 'Result'
 FROM Subject SU

Hope it works
