Important instruction: These questions use the last three-digit value (L3D) of individual student matrix numbers. For example, if the matrix number is CD180264 then the L3D value is 264 (since the last three digits is 264). Some data require multiplication of the L3D value, for example, 10(L3D) means 10 x L3D subject name is INDUSTRIAL ENGINEERING
