"My score was not good, but I passed."

Translation: 점수가 좋지 않지만 통과했습니다.

Also, I don't think 통과 is a good word to use here. 합격 would probably be more appropriate given that 통과 has more of a feeling of passing something into existence or gaining entrance into some area or some idea.

For instance 통과: The law was passed; I passed through the gate

And 합격: Passing a test; passing an audition

좋다 - good

좋지 않다 - not good
