May 28, Taiwan CCDE Written (400-007) 844 points, Pass

I passed the CCDE!
To be honest, since the preparation period for this certification dragged on for quite a while, I was actually feeling a bit shaky right before entering the exam room. After all, the registration fee is incredibly steep—if I hadn’t passed, it really would have been a disaster. However, the conditions at the testing center were actually quite good; the equipment ran smoothly, and I didn’t encounter any frustrating technical glitches.
In the end, I scored 844 points. While that’s not an exceptionally high score, given the difficulty level of the CCDE, I’m personally quite satisfied with the result.

Exam Resources and Preparation Tips: For this exam preparation cycle, I primarily utilized the question bank provided by passccielab.
Based on my actual experience during the exam, the hit rate of that question bank was truly impressive; I personally felt it covered roughly 90% to 95% of the material. Although I did encounter a few trickier, AI-generated questions, as long as you have a solid grasp of the core concepts—and combine that with the familiarity gained from the question bank to employ the process of elimination—you can generally identify the correct answer without getting too stuck.
