Planning my years?

One of my career goal is being an English teacher. To be an English teacher, I have to pass the teacher's exam. It's hard to get through it, I should study hard to prepare the exam.
Another one is majoring Korean Education. I would like to do double major English and Korean education.
The last one is getting a master's degree or, furthermore, being an Ed.D. To teach well, I have to learn more, so if I had an opportunity, I will be a master in English education.

This year, in 2010, I will work hard to get good grades. Getting good grades is important to pass the exam, because what we study is related to it.
I If I don't enter the army during my university life, in 2013, I will prepare the teacher's exam. It would be like my 고3 life^^;;
In 2018, if I were a teacher, I would go to the graduate school of education and would be studying hard to get a master's degree.
