Structures depth reference material

I failed on my first attempt. Starting to get things together to start preparing for fall exam. Looking at the diagnostics, Design and detailing of concrete, steel and timber structures was the main cause of my unsuccessful attempt. I am enrolled with Ppi2pass and did not find the material useful. Their handouts are copied from CERM. I would appreciate if you guys can share your thoughts on what you followed and if possible email me ( [email protected])  material related to Design and detailing of concrete, steel and timber structures.  Thanks !

EET went in to really good depth on all of those, before taking the test I'd almost thought too much depth, but it was very useful, and there were a few questions they didn't cover, but they made me familiar enough with the code to find even the things I hadn't learned.
