1) For those who have read books by above mentioned authors tell how much is the difference of context. What topics are missing in Soch Vichar and Nawein Zawiye that Punjab Rang (Faisal Jappa + Qamar Husnain)
2) Secondly what is the difference between Punjab Rag (CSS, PMS) and Rang Punjab
except that there is a slight syllabus difference but much content same between the two competitive exam and in the latter one author is writing the whole two volumes; for 200 marks may be.
Having bought SV and NZ, what I want to do is not to gather all the books and just photocopy those chapters that do not overlap. Have you done that? Can you suggest which chapters? Those who have read them can well answer my question.
