Frequently Asked Questions
Is Zoology scoring?
Yes — 70-85 for biology graduates. Diagrams, accurate classifications, and Pakistan-specific examples drive marks.
Botany or Zoology first?
Take both. They share genetics, ecology, and cell biology, so prep effort overlaps significantly.
How important is taxonomy?
Critical. Examiners often ask classification questions with two or three named examples per group.
