In the mind of a FREEK

I was wondering if there are any Personal trainers out there. I’m trying to become ACE certified by this coming October or maybe even November… I’m studying from the Basic studyguide (which is a whopping 150+$…), taking the computer based test (which is another 250$…), and I wanted to know if there’s anyone with some tips/pointers! I’m really nervous, I already am a Nursing Major so a lot of anatomy/physio is review, but I’m just nervous about what to expect and if I really need to study my ass off for this… The textbook I got is seeming to be very overwhelming as well with a lot of info overload…. So please any tips would help!!!
