Go back through your test and thoroughly review every question you answered. Once you’ve done that, keep doing practice questions from any source you can find. If you’re finding that you’re still not consistently scoring to where you want, push back your exam date. Don’t rush your exam and score poorly and have that score follow you around (speaking from personal experience..). If it was just a bad testing day, take a day to relax and mentally refocus. You know you can do this; just trust the process and keep grinding!
How many hours can you study between now and then? I would recommend trying to study as much as possible over the next week, then take one more FL. Then figure out if you should cancel your exam or not.
Look back at the test to see what you got wrong and what you need to focus on. Take a few more FL tests throughout the week. I was in a similar position with my lowest practice score on the aamc fl2 (494) the week before I took the MCAT but I ended up with a 505 on the actual test.
Take way more than 2 full-lengths. If you're not feeling ready or haven't changed much reschedule unless you're applying this year or something.
I took like 5-6 practice tests. Got a 515.
Practice tests aren't just 'oh see how my studying went' -- they are a tool to improve and get used to the format, pacing, and the fact you are taking a 7 hour test.
Plenty of people get into many diff osteo schools with 496+.
I know someone who got into PCOM-GA with a 495, after failing to get into VCOM through an SMP.
