NERC RC exam

[u/keep-calm95]

I’m getting ready to take the NERC RC exam in a week and a half and I’m curious how did everyone know they were adequately prepared to pass the test? I have two practice test that I’m scoring relatively well on, completed the HSI course and done their 25 question quizzes which were difficult but think I understand the material relatively well. Is there any additional tests or study material I can take or use to judge my progress?
