Questions

When do I get access?

Straight away. Checkout takes you to your course, and the receipt email has the same link.

Can I get a refund?

Yes. Full refund within 14 days of buying, for any reason, unless you have finished both timed practice exams for any course in your order. One refund per customer. See the refund terms.

How long do I keep access?

For as long as we offer the course, and at least 3 years. Updates are included, so if American Welding Society moves this exam to a newer code edition while you have access, your course moves with it.

What is the difference between the practice pack and the course?

The practice pack is the question bank and the timed practice exams. The course adds a lesson for every task in American Welding Society's content outline, worked calculations, a study plan built from your diagnostic and an exam-day checklist. If any domain scored under about 60%, take the course.

Are the questions copied from the exam?

No. Every question is original and written to American Welding Society's published content outline. Exam content is confidential and we never use it. We are not affiliated with or endorsed by American Welding Society.

Can my employer pay?

Yes. Pay at checkout and we email a receipt you can expense, or download a reimbursement request to send your manager.

Can you promise I will pass?

No, and nobody honest can. What we promise is the content listed above.
