So I failed my first SPD test and I need some suggestions for reading up on the content for Principles (Level2) and Materials & Technology (Level1).
I assume Materials & Technology, I can look into ballast readings for BDCS? Is that correct? If not, what chapters (or other outside reference books) would some suggest so I can better learn about different materials and technology.
Not sure how much more additional reading for the Principles area I would need. I probably will re-read the chapter 27 in Ballast about human comfort...Any suggestions for additional reading during my two month break would help!
Thank you in advance!
