Yes, you do need to pay $130 per exam attempt. The retake policy is on Page 8 of the Certification Handbook. You have up to 6 attempts to pass the exam, with a specific schedule as to when you are permitted to make each additional attempt. Hope this helps!
The pass threshold depends on the exam subject and is not disclosed. You will be told at the end of the exam if you passed or not, but will not be told how many or which questions you missed.
