Published by the Punjab Curriculum & Textbook Board, this is the official 11th class Biology textbook used across Punjab board schools for Class 11. Intermediate Biology deepens into cell biology, genetics, and physiology, with far more emphasis on mechanism and process than the more descriptive Matric syllabus.
Since PCTB sets one prescribed edition for the whole province, this copy is valid whether your school falls under Lahore, Multan, Gujranwala, Faisalabad, Sargodha, Rawalpindi, Bahawalpur, DG Khan, or Sahiwal board.

How to Use This Textbook Effectively
Build a process-flow understanding
For topics like respiration or protein synthesis, sketch out the full step-by-step flow yourself rather than memorising isolated facts.
Connect structure to function
Intermediate Biology questions often test *why* a structure is shaped the way it is — always tie anatomy back to the function it performs.
Practice genetics problems
Punnett-square and inheritance-ratio questions are a guaranteed paper component — practice enough variations to be fast and accurate.
