Note :  1.   In Part-III five mark questions no subdivisions are allowed.

 

2.  In Part-IV ten mark questions there should be two sub divisions each with 5 marks.

 

3.  60% of the total layout of questions (for 233 marks) must be asked from self evaluation questions of all branches of chemistry (Inorganic, Physical and Organic) in equal propotions.

 

4.  Problems can be asked from any lesson or chapter instead of descriptive questions and vice versa.

 

5.   Problems

Part – I       MCQ 4 questions             4 x 1 = 4 (1+2+1)

Part – II      3 questions                     3 x 3 = 9 (1+1+1)
