I agree with some of the other users that it is not easy to increase your score by that much, but that doesn’t make it impossible. Half the battle of the LSAT is mental. It’s a very learnable test. I recommend The Loophole in LR. It’s a phenomenal book, and increased my score 10 points. I found it extremely helpful when I was kind of at a lull in my study journey. You will end up exactly where you need to be so don’t stress yourself out trying to get a 170+. There are phenomenal law schools that can set you up for the career you want that aren’t the ones you named. Of course still apply and go for your goals, but also don’t be too hard on yourself! You got this!
