I love computer science the most of all. It's just fun to design, code, and execute programs that I made myself. Everything makes sense to me and it's easy to do, at least for me. Sometimes, I'll have problems coding, but I'll eventually find any mistakes. And trust me, I've made dozens of mistakes, like dividing by 0 in a grading program. XD
My most hated subject is history and english. I found these classes to be extremely boring. I'm a slow reader and writer, so it was a pain in the ass reading and writing for these classes.
