Chemical Engineering PE Exam Study Question

[DCall781]

Hello All,
I have been approved to sit for the Chem PE exam in MA and would like to know your thoughts regarding study materials. Is the following collection of material sufficient to prepare for the exam:
1. Chemical Engineering Reference Manual, seventh edition by Michael Lindeburg
2. Practice Problems for the Chemical PE exam, seventh edition by Michael Lindeburg
3. NCEES Practice Test
4. NCEES Reference manual

I would 't mind hearing additional thoughts on the exam from recent takers. Any thoughts are appreciated.

Thanks all,
DC
