history: A few years ago, I graduated college and took the test to earn my teacher certification. I passed, and was able to quickly get a job. I am so happy I was able to pass my teacher certification test and become an English teacher. That's great. Teachers are so important.
current: It's such a fulfilling job. The test was difficult, but I spent a lot of my free time studying for it.
next: I wanted to become a teacher before. I was afraid of how hard it would be.
