    Amazing sir g…i need these mcqs in pdf plzz …. please share me in email these all mcqs of chemistry from fsc to BS PLZZZ SIR plzz

    1. Umair Ali khan

      These MCQs are not available in pdf. Material is taken from different sources, students requested or from past papers and put on the website randomly without writing in pdf.

  2. M bialal

    sir where are the lectures mcqs of other chapters of pmc chemistry explanation ?
