So I just got my passing score on MD 101 yesterday and honestly I'm still kind of in shock. Failed my first attempt back in March with a 673 (passing is 700) and I was devastated. I'd been studying for about six weeks using just the official Microsoft docs and figured that would be enough. Spoiler: it wasn't.
The second time around I completely changed my approach. I spent about four weeks going through a proper MD 101 practice test set every single day, at least 30-40 questions. What really helped was focusing on the areas I kept missing — Intune device compliance policies and conditional access configurations wrecked me on the first exam. The study guide I used this time broke those down way better than the Microsoft docs alone.
If you're preparing right now, my biggest exam tip is don't just memorize features — understand the WHY behind each policy setting. The questions are scenario-based and they will absolutely trick you if you're just pattern-matching. Happy to answer questions if anyone's in the same boat I was.
