Not too easy. Not too difficult.
Biology is a nice and easy class. It may be difficult sometimes but studying won't make it so hard.
I learned about the structure of DNA, the way of life of some animals, the history of cells and how the world came to be, I also learned a lot about genes.

Advice for students:
Study and get good grades, don't fool around in class. Pay attention and it won't be hard for you. Also if you still don't understand ask the teacher or someone that is good in the class to help you.
