Okay so 2nd re-write Exam Experience:
Before I get into the second re-write lets re-cap my first write so we gleam into what I did wrong last time and what I improved on.
First Write:
First write was a interesting exam. I felt A LOT of my time was used up on figuring out the exam and how things worked. On top of that many of the design or drag-n-drop I was re-reading a few times to make sure I understood everything as they wanted. Another thing I did wrong was I wasted way to much time on some of the multiple choice questions. Lastly due to poor time management I ran out of time missing, 1 drag-n-drop, 1 design question, and 10 other questions. My final score on my first exam was 276. Something tells me last time had I been able to finish I might of squeaked by on that one, but no one will ever know :smileysilly:
Conclusion:
- Time management was poor, ran out of time and didn't get to finish all questions on the test
- Spent to much time on the design / drag-n-drop absorbed time I couldn't afford.
- Spent to much time on 1 point mulitple choice questions, especially the calculation ones as I knew most of them, but the time it took to calculate everything could of been better spent elsewhere
Second Write:
Second write I went in with knowledge from the first exam so I was familiar with the tools, so time was saved there. I went in with a different time management plan this time. My plan was to mark the longer multiple choice questions for review then come back to them once I finished everything else to insure I finished all the drag-n-drop and design questions this time as they are worth the most points. My study material was more precise this time around with material I felt was more of the core pieces which would be picked on.
So the first thing that went wrong was my time management. Even with the new plan to skip the longer multiple choice questions I found myself still giving them around 1 min - 2min then flagging them for review and moving on. Something in my brain just wouldn't let me pass an question unread :smileysilly: This will need to be corrected :smileysilly: However the time I saved with being more familiar with the tool seems to absorb this extra time spent. The next thing wrong with my time management was even though I was holding my self accountable to 2min a question except for Drag-n-Drop and Design questions. Even my time being managed this way I still found myself rushing. I know on one of the Design Questions I'm pretty sure I could of done a much better job on the connections however I had the question completed, glanced at it, then looked at that ever looming clock counting down and figured "it would have to do" as I didn't want to waste anymore time re-doing a large portion of the question. Long story short I went in with a better plan but still faltered on some parts of the execution. However this time around I did finish ALL the questions and got to see the review screen 
I had about 40min left after finishing everything so I had time to double back to some of my longer multiple choice questions again, but not all. However again even with doubling back to re-read and calculate the calculation questions I found myself constantly obsessed with the time. In my mind it was better to get through as many of the questions I had flagged with that 40min as possible with a rushed effort then taking my time with each one. I figured the numbers where better if I managed to touch all the questions again even if it was fast effort opposed to taking my time with say 5-10 out of the 50+ I flagged. Now I don't know if this helped or hurt me, guess we'll never know.
So what did I do better:
- I managed my time better, as I was able to finish the exam. This was not without fault however
- I believe I did a much better job on the design questions and drag-n-drop questions.
What do I need to still work on :
- Better time management, with more focus
- Calculate cluster sizing faster
- Better manage / answer Multiple choice questions
The end result was I sadly missed the passing score again with a 290 
So close but yet so far away. This stung a little however failure is a good thing sometimes as it resets your expectations and can be the fuel for success. Good things came out of the last failure, as had I not failed the DCD on my first attempt the simulator and extra material I built for myself and the community would of never been built. I will go back to the drawing board and re-adjust my questions and focal points. Most of all I will hopefully find an answer to the biggest question I have now. Which is what do I study from here? I have read over ALL the material at least 3 times.... if not more. So even though the exam points out the sections you struggled with, these are all sections I have read over many times. So when I find the answers I'm looking for I'll be sure to update this forum and simulator with some new questions that will hopefully better assist people who which to challenge this exam.
Sorry I don't have better news but that's the way the cookie crumbles sometimes :smileysilly:
Cheers and good luck to anyone else preparing or taking a test in the near future!
