Write a letter to your friend telling him or her about the course you intend to pursue when you enter senior high and give reasons.

Dear Susan,

I hope you are doing well. Next year I am starting senior high school, and after considering all the course options, I decided to take Biology since it is the course that best fits my interests.

When I was a little boy, I liked spending time in the backyard exploring the different insects and plants there. My love for plants and animals has only increased since then. Taking Biology will increase my knowledge about all the living things that surround us, helping me understand how they work and interact with each other.

The other reason to take Biology is that I want to pursue a career in Natural Sciences. I hope to study Biology and Genetics in college and work as a researcher in a prestigious laboratory. By enrolling in Biology, I would gain crucial knowledge for college and my professional life.

I have to go now, but tell me about you. What course are you going to take in senior high? Do you still love Maths?.

I'm looking forward to hearing from you.

All the best,

Karl.
