The 12th class Biology textbook is the official book published by the Punjab Curriculum & Textbook Board (PCTB) for Class 12, and it's what every Punjab board school actually teaches from. Intermediate Biology deepens into cell biology, genetics, and physiology, with far more emphasis on mechanism and process than the more descriptive Matric syllabus.
Lahore, Gujranwala, Faisalabad, Multan, Sargodha, Rawalpindi, Bahawalpur, DG Khan, and Sahiwal boards all use this same PCTB edition, so it applies regardless of which board your school is registered under.

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.
