I'd say "저는 제가 말할 수 있는 것 보다 더 이해할 수 있어요." meaning your listening skill is better than speaking.:) \^o^/

I may be joining your learning Korean beginner's club as well. Have you ever done a Vark test to see your learning style ? My style is basically read and write, not listen so speaking is going to be challenging. Korean text is very distinctive isn't it ? You will enjoy your first trip to Korea, it is an interesting culture.
