BISE Lahore 12th class Guess papers for Biology

Biology is a tough subject for the intermediate science group. It’s a study field in which students learn about living organisms, including their structural functions and growth. It is one of the most interesting subjects to read and a difficult one for Fsc pre-medical students. At this stage those students who are searching for some helping materials for biology, we have collected biology guess papers for the 12th class. As everyone knows, that upcoming month can be an exam month for intermediate part 2 students.

Every student knows the importance of past papers from an exam point of view, and we collect some most important and repeated biology questions. Students should prepare these questions before attempting the 12th class annual exam 2015.
