Hi! I was in the same boat as you. I was stuck at around a 501 a month before my exam and even up until a week before, and just got my 508 score back yesterday. So I definitely understand the frustration but I’m here to hopefully give you hope! My main focus a month before was as much AAMC practice as you can do and reviewing it well by writing down any information you didn’t know or how to get it right next time. I would also re-read those notes before bed. I also read through the KA 86 page P/S doc. I also focused more on my lowest sections (CARS and B/B) bc I figured it’d be easier to bump up my score in those, than get my other 2 scores into the 130’s, plus it would make my score more well rounded. More than anything, I tried to understand more about how the test would ask me questions and how to find the answers to the questions in the passage or find hints in the question stem. I think this was the biggest game changer for me. Definitely only do this with AAMC practice material since it will be the most similar to the real thing. You can definitely do it! I hope this helped :)
