10th Class Biological Science S.A.-1 (EM) C.C.E Model Paper


Biology not only provides students the knowledge about life and living
organisms, but also is the most scoring subject in Science stream. The
study of Biology brings about an awareness of the rich diversity of life
forms that inhabit the Planet Earth. It helps students to know and

more effectively with a wide range of routine concerns such as
nutrition, dieting, health care, proper use of medicines and care of
domestic animals and plants.

Exam Pattern

Biology subject will have 50 marks; and the
examination duration is 2.30 hours in addition to 15 minutes for reading
