I made a instruction on my own in order to practice my writing.
INSTRUCTION : What do you want for you major? Use specific reasons and examples to explain your position.
Handong Global universty has many college courses which I want to major in. Economics is one of them, in fact, the special one. Although I haven't decided my majors yet, the number of which is recommended to be two, I have almost made a decision in one major, economics. Not only useful, economics is very interesting subject to study.
First of all, economics is very logical field compared to other social sciences. This is because many economists are using mathematics in order to develop their economic theory. Before entering university, I thought I will never use my highshool mathematics knowledges such as differentiation. But when I studied economics in my sophomore, the knowledges was very helpful that I could relatively easily focus on the economics itself, while my friends who didn't studied differentiation in highschool were having trouble dealing with mathematics. Mathematics is not a nucleus of economics but a tool of it. This tool, however, makes economics more logical and reasonable subject than any other social sciences.
Another reason I believe economics is exciting subject is that it tries to analyze human's behaviour. Because economics is a subject about human society, it explores how people act when specific situation occurs. For example, in my gametheory class, I had examined various decision making situations such as soccer versus opera, and confession versus not-confession. Unlike another subject, the significant characteristic of economics is that it analyzes human mind with mathematics. Some fields of scholarship such as psychology studies same thing but don't use mathematics that it is less scientific than those use mathematics. Others such as physics use mathematics but it doesn't explore human mind. That is, it is only enonomics that studies human mind with a scientific tool, the mathematics.
For these reasons, I think it is good for me to major in enconomics. It is fine way of studying humans and events occur in their society with mathematical tools. I'm looking forward to returning to the university and studying economics in next spring semester.
I want you to advise me for more desirable or polished form of sentences. Thank you :)
