I currently have access to the follow study materials for PPD/PDD:
Kaplan 4.0 BDSC, BS, SS = 750+ pages
Ballast 4.0 = 500+ pages
Ballast 5.0 = 1000+ pages
Architectural Graphic Standards, 11th edition (student edition) = 560 pages
Mechanical and Electrical Equipment for Buildings, 11th Edition = 1800 pages
Building Codes Illustrated = 480 pages
Fundamentals of Building Construction = 1000 pages
Building Construction Illustrated = 480 pages
I plan to start by doing all kaplan 4.0 material while also skimming through Building Codes Illustrated, Building Construction Illustrated. Then before taking an exam I will review the exam's chapters in ballast 5.0. That leaves me with ballast 4.0, which I'll only use for the questions, Architectural Graphic Standards (do I need to look at this or is Building Construction Illustrated about the same thing), Mechanical and Electrical Equipment for Buildings (this book is huge what parts should I study?), and Fundamentals of Building Construction (again is this necessary or is Building Construction Illustrated about the same?).
