Top Scoring Tips for Punjab:

  • Textbook Reading: The paper is 100% derived from PCTB books. Do not rely only on keybooks.
  • Objective Paper (20%): The objective section is the easiest way to lose or gain marks. Practice these online MCQs repeatedly as they are taken from 5-Year Past Papers.
  • Bubble Sheet: Ensure you know how to fill the OMR sheet correctly. A double-filled bubble gets zero marks.
  • Pairing Scheme: Check the latest pairing scheme on GoTest to know which chapters have the most weightage in the objective section.
