Also, it's totally possible to reach your goal; I've seen lots of 7Sagers climb 10+ points. I'd recommend being on some of the calls with BR groups so that you can get a sense of how they do it since proper BR is key to increasing your score.
@Thoughtful it is not the number of hours you spend studying that matters, it is how well you utilize your study time that does (i.e. how proper your study methods are).
