Closing up big BR gap to get into 170s

I’ve been studying since late May and I’m planing on taking the September LSat. I study for most of the day, 4-6 hours 5-6 days a week, and meet with a tutor twice a week. I take a pt every 2 weeks. My first 3 pts were really encouraging because I’ve gone up about 10ish points overall, about 5 points between each pt. But my last 3 pts I’ve hit a platuea all in the high 150s. No matter what method I try, ones my tutor gave, ai, once’s a read online, from friends nothing will increase my score under timed conditions. Everyone said br indicates your real capabilities, and I BR in the low to mid 170s every time. This month long plateau is super discouraging. With all the study and tutor help I get, I didn’t see how else I can increase my score. Does anyone have any tips to close the gap bc I’d hate to apply to law school with a high 150 if I’m capable of getting in the 170s. Am I capable of closing this gap in one month, or should I postpone the test? Or is postponing just postponing the inevitable and I should just accept my score as it is? Please looking for any suggestions!
