I am glad to have your concern. I've made no attempts at notes as yet. I am doing study for the-sake-of-study nowadays (2012 is not mine). However following are the observation that I've made. That:

a) Ms Sheher Bano's books are already 'on the level' of notes. If you study both parts comprehensively I can guarantee you of 60 pc marks (i.e. 120/200); and the reason these won't go beyond this range is that these are made to fulfill 14 years requirement for education. Whereas in CSS syllabus it is mentioned that honours/masters course is the requirement.

b) combining them with VU notes you're as good as 130-135, provided you do not take objective portion lightly

c) If you want 135+ then you must consult works by foreign authors and search internet for it. For example the notes of David Myers are available online.

d) an interest in the subject makes the journey easy

Rest assured that whenever I've a useful material, I'll share w/o anybody having to question.

Take care.
