Hello, Polly.
Today's talking is below.

I took an exam for Chinese character in Korean last Saturday.
Chinese character test is to check my knowledge about Chinese character.
It is one of the keys to get a job so I needed it.
I prepared that for 3 days. I concentrated preparation for the exam.
The test is not easy. But I guessed over a few questions, I could give the correct answer to the question fortunately.
I marked my papers just after finishing the exam
Maybe I'll pass it because I have a score over 70.    <- Please correct it to better senstence.
If I have it over 70, I can get a certification.

You asked me if you can't pass it, what will you do next?
If I can't pass the exam, I'll retake it after a few days.

fortunately, I don't need to retake this exam.



Thank you for your class today.
Have a nice day.
