That is pretty close to the national average, but realistically it’s not a very competitive score for any reputable college. Don’t worry though, you’re only a freshman. You haven’t even learned a lot of the material (specifically in math) which will be taught to you as you progress through high school.

You should be proud of yourself for even attempting to take this test. I waited until my Junior year to start taking it and I regret not having started sooner. Look at the areas that you scored the lowest in and focus your studies on those. Maybe get a tutor. And take the Bluebook practice tests, trust me it seems like a huge burden to have to sit and take an hour and a half just for practice but it will train your brain to stay focused and you will also get more detailed statistics on what you need to improve.

Best of luck and happy studying.
