ACT考试用英语考试吗？

that shows your study is , how to say ,not too good, not too bad, maybe you are a bit over average, just try to find what your disadvantage is and make it better.

and i don't know which level you are in and what kind of problems, so it's a little difficult to answer your question exactly.

hope you make a progress in your study, not only in E, but also other subjects!

:) and have a good hay!
