Cwa exam application query

I think.. exemption applies to CS qualified students or to old syllabus students who get exemption of few subjects from appearing..., and regd carry forward... if you got 60 or more in any subject and couldnt clear in other subjects, then 50 marks of subject, in which you scored 60 or more, will be carried forward while calculating aggregate in next attempt... This is my view... but not cent percent sure..., I too will wait for experts answer...
