CCDE Written, Finally Cleared

The 400-007 written is a different beast and I don't think any single resource gets you through it. That said, the nwexam practice exams gave me the scenario-based practice I couldn't find elsewhere. The business-outcome style questions trained me to think like a design expert rather than an implementer. I used it alongside the official reading list for about four months, attempting full timed mocks every weekend. Passed on the first try. For the written stage, this was genuinely the most useful prep I had.
