PDD Fail

Hey everyone, PDD is my last exam and i just recieved the fail this morning. I recieved a level 3 in integration of building materials and systems and a level 3 in construction documentation. I used amber videos, bci, building codes illustrated, jenny notes, ppi practice exams and designer hacks. I felt very prepared for PPD and passed on ny first try but for this one i felt like i didnt get into enough detail for what i was being asked. Does anyone have any recommendations on what sources i should use to study for these 2 content areas?
