  , max(CASE WHEN SUBJECTCODE = 'CMP-126' THEN TOTAL END) AS [CMP-126(TOTAL)]
  , max(CASE WHEN SUBJECTCODE = 'CMP-126' THEN GRADE END) AS [CMP-126(GRADE)]
  , max(CASE WHEN SUBJECTCODE = 'CMT-121' THEN IMS   END) AS [CMT-121(IMS)]
  , max(CASE WHEN SUBJECTCODE = 'CMT-121' THEN EMS   END) AS [CMT-121(EMS)]

to the above you may want to include:

WHERE SUBJECTCODE IN ('CMP-126','CMT-121')

You need max() to allow summation of many rows into one row
in this query max() will not amend or affect the data
it simply allows summation to a single row per UID

compare a query with max() and one without max() here:
http://sqlfiddle.com/#!3/4d532/1

without max() it really much the same as your base table.

>>fetching null
if there is a null in the source data you would get a null in a "cell" of the output
not sure what you mean really.

PortletPaulfreelancerCommented:
What grade should I award?
C should only be given for an incomplete solution that does not fully address or answer the question ... The asker must justify giving a C grade
@searchsanjaysharma I would very much appreciate knowing what was incomplete with my answer.

I shall request attention on this so it does not auto-close.
