FAQ

Can I try it before I pay?

Yes. Open the study dashboard free with no signup, or take any exam's free practice test. You only pay when you want the full question bank, timed simulations and every study tool.

What if I buy it and it's not for me?

Because you get the full question bank and study materials the moment you pay, all sales are final. Try the free test and the free dashboard first so you know it suits you. The one exception is the Pass Guarantee: complete the full prep, and if you still fail, we refund 100%.

Can I get a refund if I change my mind?

No. Because you get the full question bank and study materials the moment you pay, all sales are final. Try the free test and the free dashboard first so you know it suits you. The one exception is the Pass Guarantee: complete the full prep, and if you still fail, we refund 100%.

What if I study and still fail?

That's what the Pass Guarantee is for. Answer every question in the bank, read every study topic, pass 2 timed simulations and reach a Readiness Score of 80, then sit your exam within 60 days. If you don't pass, send your result notice within 30 days and we refund 100%.

How long do I keep access?

For as long as your Premium subscription is active. Cancel any time from your account and you keep access until the end of the month you've paid for.

Is the content up to date?

We check each exam page against the current AWS CWI page, program price list, Examination User Guide and Exam References and Editions Guide, and show the date it was last checked. In 2026 that included the US$1,255 member / US$1,520 non-member exam fee, the 72% pass mark on each part, and the D1.1/D1.1M:2025 edition listed in the 20 Oct 2026 references guide.

Are these real exam questions?

No one can legally sell the actual exam questions. Ours are original questions written to match the AWS B5.1 content areas, the free Part B Book of Specifications and the D1.1 code, with an explanation for every answer and the clause or calculation behind it, so you can check our work.

Do I still need the code book and the Book of Specifications?

Yes. Part C is open book, so you need the code you chose, and Part B is answered from the AWS Book of Specifications, which AWS provides free to download and supplies on exam day. We're the extra practice: more questions, timed mock exams, flashcards and a Readiness Score so you know when you're ready.

Which exam should I study first?

AWS requires Part B first. Parts A and C follow at a Prometric center within 120 days of Part B, in either order. Most candidates study Part A and the code book together, because the terms and symbols carry over.

Does one plan cover every exam?

Premium is per exam: one plan covers the CWI part you pick at checkout, Part A, Part B or Part C (D1.1). Preparing for more than one part? Add a plan for each, and cancel each in two clicks when you're done.

What does Premium include?

Everything for the exam you choose, for as long as your subscription is active: the question bank, timed simulations, study notes, flashcards with spaced repetition, mind maps, video lessons as they release, your mistakes bank, detailed reports, the Readiness Score, all 5 bonuses and the Pass Guarantee.

How does the Pass Guarantee work?

Complete the full prep for your exam: answer every question in the bank, read every study topic, finish 2 timed simulations with your latest at or above the pass mark, and reach a Readiness Score of 80. Then sit your exam within 60 days while your access is active. If you don't pass, email us your official result notice within 30 days and we refund 100% of what you paid. Your dashboard tracks every requirement live.

What's the Readiness Score?

A 0 to 100 score on your dashboard that combines your accuracy, how much of the bank you've covered, your timed simulation results and your flashcard mastery. Reaching 80 takes consistent above-pass-mark work across the whole bank, which is why it is the bar for our guarantee.

What do I get with a free account?

Your saved free-test results, a starter Readiness Score, the first study-notes topic and flashcards for every exam, the mind map outline, your mistakes bank and the CWI Formula & Values Sheet. Upgrade any time to unlock the exam you're taking.

Is it a subscription?

Yes. Premium is $147 a month per exam (about $4.83 a day) and renews monthly until you cancel. You can cancel in two clicks from your account, and there's no minimum term. Most people study for 1 to 3 months. If you want a whole year for one exam, the yearly plan is $1,323 for 12 months (3 months free) and renews once a year until you cancel.

Can I get free access by referring friends?

Yes. Every account, including free ones, gets a personal referral link in the dashboard. Share it anywhere. Each person who signs up through your link and buys a plan earns you a referral ticket, and each ticket unlocks any exam of your choice for 14 days.

Can my employer pay?

Yes. Many fabricators, inspection firms and contractors pay for CWI preparation, because contracts and codes often call for a qualified inspector. Check out with your work email and we'll send a receipt you can expense.

Can I study on my phone?

Yes. Everything works on phone, tablet and computer, and your progress syncs to your account.

Are you affiliated with AWS?

No. CWIQuizBank is an independent exam-prep company, not affiliated with or endorsed by the American Welding Society or Prometric. AWS, American Welding Society, CWI and Certified Welding Inspector are marks of the American Welding Society, used only to describe the exam we help you prepare for.
