My english speaking test results (나의 영어 말하기 시험 결과)
- 203
- 3
- 2
I upgraded 1 grade.
(한 등급 올랐어요.)
I am satisfied with that result.
(저는 그 결과에 만족해요.)
I feel I need to practice more and more.
(저는 더욱더 연습할 필요가 있다고 느껴요.)
No matter how busy I am,
(아무리 바빠도,)
I will do my best efforts so I will get perfect score before long.
(최선을 다해서 머지않아 만점을 받을 거에요.)

I upgraded advanced 1 grade.
When using "grade" in the sense of a school grade, etc, you would say advanced not upgraded (although logically that would make sense, but English doesn't always make a lot of sense).
I am satisfied with that the/my results.
I feel I need to practice more and more.
If you wanted to use "more and more", you could say, "I feel I should practice more and more everyday."
I will do my best efforts so I will get a perfect score before long.
I will put forth my best effort so that I will, in due time, get a perfect score before long.
