- Certification: IASSC Certified Lean Six Sigma Yellow Belt (ICYB)
- Vendor: Six Sigma
- Free on this page: 6 practice questions with answers and explanations
- Full practice set: 150 questions
Treat this sample as a diagnostic. Answer honestly, check the explanation after every question, and note which topics feel shaky. A short, focused review of those topics is worth more than re-reading everything — and the full set lets you drill them topic by topic.
A good way to use this page: take the whole sample in one sitting, then go back over every explanation with fresh eyes. Mark the topics that felt uncertain, not just the ones you got wrong — uncertain answers are unmarked risk on the real exam. One or two focused passes like this usually move a score more than days of passive reading.
Inside the full ICYB practice set:
- All 150 questions with answers and explanations
- Timed Exam Simulation that mirrors the real exam pressure
- Topic Training to drill one domain at a time
- Ask AI for More Explanation on every question
- Flag questions and review them before you finish
