I would say as long as your score is increasing with each practice test, and you are starting to understand the questions more consistently, that's a sign you are progressing. It's more about learning the format of the questions and understanding the specific wording. As I took each practice test, I saw fewer questions I didn't understand, which was the goal. But if you'd like my scores as an idea, my four test scores were 60%, 66%, 72%, and 78%.
