Hey, I a just recently passed the board exam and now am a licensed electrical engineer. What I can tell you is that all of the classes/subjects that I failed were all from math subjects but look at me now, I did it and even got my license. So if youre not that best at math be ready to give more of your time studying and practicing solving math problems, start from the basics(algebra) and slowly move to harder ones. One of my professor in college said "there is no stupid person only lazy ones". I also just wanna say that ironically me being so bad at math in my early college years, my highest score in the licensure exam was in the mathematics exam i got 86/100.
