Biology 9th class

As you know Biology is all fun if you know how to enjoy it. I enjoyed it really well in 9th Class when I got 73/75 in Sahiwal Board. My formula was to clear your concepts and diagrams, get the unexpected marks. The topics that were difficult for me, I made use of google to see the animation. Biology includes concepts, diagrams and you will get a lot of marks.
