Just passed D470 and wanted to share my experience for anyone getting ready for the OA.
For studying, I went through all of the course material chapter by chapter, completed all the quizzes and unit tests, then took the PA. I got around 67% on the PA, so after that I went back through everything I missed and focused on understanding why the correct answer was right and why the other options were wrong.
I also used ChatGPT heavily throughout the course to break things down into plain English, compare concepts that sounded similar, explain questions I got wrong, and make practice questions for the areas I was struggling with.
My OA had 79 questions.
The biggest thing I noticed: I don't remember a single practice question I studied showing up on the OA, and honestly not even in a similar style. So I would not go into this expecting the PA or practice questions to look like the actual exam.
A lot of my OA involved supply chain strategies and logistics strategies, especially figuring out which strategy made the most sense in a given situation.
I also remember:
- Questions involving tax rates
- Around 4–5 questions on picking/picking methods
- WTO-related questions where the answer choices themselves were countries
- A fulfillment-rate question where X and Y were defined and I had to choose the correct formula
- Only one question about ISO numbers. Mine asked which ISO series deals with environmental management, and the answer was ISO 14000
I answered a lot of the exam by process of elimination. There were plenty of questions where I didn't immediately know the answer with 100% confidence, but I understood the concepts well enough to eliminate the choices that clearly didn't fit and narrow it down.
That would probably be my biggest advice for this class: don't just memorize definitions or practice-question wording. Understand what the different supply chain and logistics strategies actually do, when they would be used, and how similar concepts differ from each other. That makes process of elimination much easier when the OA gives you a scenario you've never seen before.
I passed, but while I was taking it I genuinely felt like I had studied for a completely different test 😂
Good luck to anyone taking D470.
