As you know Biology is all fun if you know how to play it. I played it really well in 9th Class when I got 74/75 in FBISE. My formula was simple clear your concepts and diagrams, get the unexpected marks. The topics that were difficult for me, I made use of Google and Youtube to see the animation.
On the exam day, I just wrote a few lines and a diagram to the answer of each question. Even I knew 1% about a thing, I applied for the same role. Due to this reason, I had been getting great marks in SSC and HSSC in Biology.
These notes have 9 chapters, every chapter is well explained with short questions and long questions. You don't need a guide if you get these notes. These are far better than having a guide.

CHAPTER 1: INTRODUCTION TO BIOLOGY

CHAPTER 4: CELL AND TISSUES


This chapter is the longest chapter of 9th class, and it is difficult to most of the students. Here is a tip for you that I did in 9th class as I got 74/75 in FBISE. I memorized all the diagrams and cleared my concepts from Youtube and Google Image. In the exams, I just wrote a line and a diagram. I just knew the concepts and the diagrams. I didn't do parrot fashion (ratta'lization). Federal Board is really good when it comes to giving marks based on your concepts :)

As the name suggests, it is all about how a cell deals with energy. How it is formed, and broken down to run the cell activities. Then the role of ATP is discussed. The most important question is 'the mechanism of photosynthesis: light and dark reactions.'

 CHAPTER 9: TRANSPORT


You might be curious that is it about transportation how a car goes from city to another? How fast an airplane flies. Why the bullet train of Japan is faster than the Pakistani train? No! It is about the cell.  How materials are transported from one cell to another. How it happens in plants, and human beings. The most important question is of heart, what is its structure and how it works. Just memorize the diagram, and learn 8 important sentences on which you make a short heading. You can get the good marks. Keep a good eye on the diagram.
