I have the option of taking my Lean Six Sigma Black Belt Certification exam online at home or going to a testing center. Trying to figure out which is better for me.
Arguments for online:
- No commute stress
- Familiar environment
- More flexible scheduling
Arguments for testing center:
- No home distractions
- More controlled environment
- Better equipment potentially
My main concern with the online version is proctoring — I've heard some certification exams have very strict rules about what's allowed in the room. One wrong move and you're flagged.
Has anyone taken LEAN both ways? Or specifically the online version? How was the experience? And does the difficulty or question format actually differ based on how you take it?
Also — any issues with the "lean manufacturing" type content being harder in one format vs the other?
Same boat a few months ago. Here's what I'd tell myself:
The LEAN exam is more concept-focused than the study guides suggest. They test whether you understand lean manufacturing, not just whether you can define it.
My tip: when you see a scenario question, mentally walk through it step by step before looking at the answers. The wrong answers are designed to catch people who jump to conclusions.
Good luck — the fact that you're doing this level of prep means you're going to be fine.
