                In case of Inter-Subject Scaling/Moderation ,  When  they says that it is done to bring balance between marks of different subjects it should be reflected in final results. But the case is not so which can be seen by analysis of data of Civil Services (Main) Examination-2007 which  shows that no balance  is achieved between all optional subjects  after applying statistical moderation by Linear Transformation Method as the Mean marks ranges from 210(Physics) to 333(Maithili Literature), Minimum marks ranges from 0 to 376(Arabic literature) , Maximum marks ranges from 258(French literature) to 406 (Zoology).  Thus, the whole process has lost its way in the maze of statistics applied without proper application of mind.
