I teach a Pharm Tech class, and my students use a book called:
Pharmacy Certified Technician Training Manual
Editors
James Lil, PharmD
Dianne Miller, R.Ph
Jennifer Pakkala, B.A.
8th Edition 2001
Published by Michigan Pharmacists Association
I am not familiar with those you had mentioned...but I recommend just doing as many practice tests as possible and the questions fill in the blanks for much of the covered materials.
Hope that helps.
