Sorry, you are already studying in the U.S. as a 10th grader? Where are you studying and where would you like to apply to? Since you are already studying in the U.S. you may not need to worry about your TOEFL score but if your English standard is not good enough, the schools which you plan to apply to will know right away. So I think you will need to work on your English level because 85 on TOEFL is not what U.S. schools will expect from someone who is already attending school there.。
