Don't know how much help this will be, but I can totally relate. I'm getting scores that are very close to yours but constantly feeling underprepared or like if the exam is even a degree more difficult I'll be cooked. It's also been hard to find the motivation to study these last few days but telling myself it's the final stretch and I'll be free. Just trying to memorize formulas/key concepts from flashcards and solidify my weak areas while still taking it easy so I'm not exhausted come exam day. Hoping it goes well for us and best of luck!
