ATI testing CUI ABSN

Hello! I am in an accelerated BSN program and need some help or tips on how to pass ATI exams. At the end of each course we have to take ATI and it counts as 10% of our total grade. I already took pharm and fundamentals ATI but they were so hard. I am nervous for the advance med surg and mental health ATI. Does anyone have any study tips or know of outside resources other than the ATI website and books to help prepare? I felt that the ATI website was not helpful as it was way easier than the actual ATI exam. I felt unprepared. Any info at all would be great! Thanks!
