I believe in you!! Ik you're retaking and it's stressful but you've got to go in there with the mindset that you can kill it 🙂. Review the stuff you've been getting wrong and really brush up on anything you feel a little weak in. Do one or two more practice exams if you feel uncertain of your timing, 8 days is plenty of times. I say for the 2 days before you'll want to rest up and lightly review though!
