Improving your fluency is all about making sure that you are using the language as much as possible. One easy way is to try to join study groups for classes that contain native speakers. If there are any language partner programs at your school or in your area, that is another way to practice outside of class time and get feedback on your progress. Another option is join any student or community groups in the area that interest you.
If your school has an resources for helping second language learners with writing, I would encourage you to use them as well.
