A possible version:
What worries me most is whether I can pass English test in college entrance examination. I find it important to learn English well. In my opinion, success depends mainly on whether one can have great determination. My hope is that I can be admitted to a top university. However, it is a fact that I don’t do well in study.

All in all, it is our responsibility that we should spare no effort to realize our dreams.
