ati fundamentals final

So I have my fundamentals final in less then 2 weeks, I find that the book is not as informative as the online modules, I'm in an accelerated program and its soo hard to spend hrs a day, I mean hrs sometimes 5-7 at a time online studying. My first ati exam was on Pharm, I literally went insane for that test, I did every practice exam, studied the rationales, you name it, I did them over and over and honestly the final was completely different from what we practiced, I'm surprised I passed, barley but I passed. I was one of 5 people out of 30 who passed, 5!!!! Now I'm nervous for this test, we also need to pass this test to pass the class so you can understand why I'm beyond nervous. Any tips on how and what to focus on for this final?? I'm still in shock from Pharm, and I really hope that this exam is not like that, where I study all the practice exams and skills modules and the info asked is completely different.
