Chemical FE Review Handbook is a great prep resource
I got the FE Chemical Exam review handbook, which I've found very useful so far (though only 3 chapters in). I really like the general tone and layout of the information, equations, introduction of the exam, etc. I do wish there were more practice problems (with solutions) in the book. It's not too bad using practice problems on the internet and using the handbook as a reference though. Also, book showed up kind of beat up which isn't ideal at this price!
