Frequently asked questions
Straight answers about the LSSBB exam, the questions, pricing, the free trial, and how this fits your prep.
The LSSBB exam spans 9 domains - History and Background of Lean Six Sigma (5%), Green Belt Body of Knowledge (10%), Define: (Strategic planning methods and project selection) (15%), Measure (Data collection and process mapping) (10%), Analyze (Root cause and statistical analysis) (15%), Improve (Solution development and implementation) (10%), Control (Continuous improvement and sustainment) (10%), Leadership (Facilitation and change management) (5%), and Financial and business acumen (5%). Every practice question maps to one of them, so you train on exactly what's tested.
The Lean Six Sigma Black Belt (LSSBB) exam has 80 questions and is completed in 2 hours 30 minutes. Our timed practice tests mirror that length and pacing, so exam day feels familiar.
No - and that matters. These are original practice questions written to mirror the style, difficulty, and domain coverage of the LSSBB exam blueprint. We never distribute actual exam content, so practicing here keeps you fully compliant with official exam policies.
No. LSSBB Exam Prep is an independent study resource for Lean Six Sigma Black Belt (LSSBB). It is not affiliated with, sponsored by, or endorsed by the official certifying body or exam administrator.
Every paid plan unlocks the full bank of 1,000+ practice questions covering all 9 LSSBB domains - History and Background of Lean Six Sigma (5%), Green Belt Body of Knowledge (10%), Define: (Strategic planning methods and project selection) (15%), Measure (Data collection and process mapping) (10%), Analyze (Root cause and statistical analysis) (15%), Improve (Solution development and implementation) (10%), Control (Continuous improvement and sustainment) (10%), Leadership (Facilitation and change management) (5%), and Financial and business acumen (5%). You can practice the whole bank, filter by domain, or run a timed, domain-balanced exam simulation.
Yes - the bank is maintained against the current exam outline, and questions are revised when the exam changes.
No honest practice platform can guarantee a pass. What realistic practice does is show you - before exam day - exactly which domains are weak, and give you the repetitions to fix them. That's the difference between hoping you're ready and knowing where you stand.
Yes. You get 10 free sample questions with instant feedback - no credit card and no account required.
The free sample shows you the question quality. Paid plans unlock the full 1,000+ question bank, exam-style practice modes, mistake review, and - on Fast Track and Pass Confidence - progress analytics that show your readiness by domain.
No. Every plan is a single one-time payment for a fixed access window - 48 hours, 7 days, or 6 weeks. There is no auto-renewal and no recurring billing.
Match it to your exam date: Final Review (2 days) for an exam in the next day or two, Fast Track (7 days) for an exam this week, Pass Confidence (6 weeks) for a structured run-up.
For most countries, the price you see is exactly what you pay - tax is already included. Where local law requires it to be added separately, it's shown clearly at checkout before you pay, so there are never any surprise fees.
Access is instant after payment and runs for your plan's full window from that moment. When the window ends, your local progress stays on your device - you can buy another window any time and pick up where you left off.
Yes - the whole platform is mobile-first: practice, mistake review, and analytics all work on any phone, tablet, or laptop with a browser. Nothing to install.
Every answer feeds your per-domain accuracy, readiness score, and weak-area list. Instead of re-reading everything, you drill the domains that are actually costing you points - that's what moves a score in days, not months.
Chat with us any time - the 24/7 support chat in the corner of every page gives instant answers about plans, access, and billing. Prefer email? The contact link is in the footer. Payments are processed securely by Stripe, and active customers can download an invoice from their profile page.
Make sure you're signed in with the same email you used at checkout - access activates within a minute of payment. If it still doesn't appear, email us from the contact link in the footer and it'll be sorted out.

Real feedback from LSSBB candidates on Reddit.
"took me way longer than it shouldve, kept putting off the analyze section since root cause stuff always tripped me up. the practice questions on lssbbexam.com actually mirrored the scenario style on the real test. passed first try, still kinda surprised."
"honestly wasnt sure id need much prep since i already had my green belt, figured id skim thru the material. wrong. the mock exams showed how weak my define section was, strategic planning stuff especially. reworked my plan around that and it clicked eventually."
"no real hype here, just did the mistake review after each practice set and it helped me stop repeating the same errors on control questions. proctor scheduling was its own headache but the studying part went smoother than expected."
