If it were me, I would take a few months, prep hard, and move test to Jan. Be more competitive next cycle. This is not a test you want to go into unprepared. I started my first ever practice test with a 498, And didn’t take the test until I scored above 510 on FLs. Even then, I didn’t score as high as I wanted to and was disappointed. It’s a beast of a test. Make your decisions wisely. Just my opinion but you do what you are comfortable with as it is your decision to make.
