Series 86 prep guidance, PLEASE!!!!

Hi,

I would really appreciate if someone can share any tips they have or even your experience about your recent series 86 exam.
I have my exam next week and I am literally freaking out. I took 6 practice tests from STC material and scored 74% average (65-79%) on my first attempts. I have read that people who got late 80 to early 90 in practice tests still failed and I am terrified. I would appreciate any help!

Thanks!
