Best free resources for AWS prep in 2026 — compiled list

For AWS - American Welding Society Certification specifically, I found the PracticeTestGeeks explanations were detailed enough that I didn't need to buy a separate study guide. The combination of doing the practice questions + reading every explanation (for both right and wrong answers) covered most of the content I needed.

Great list. I'd add: LinkedIn Learning has some other skilled trades-related courses that overlap with cert content, and if you have a library card many libraries give free access to it. Also check if your local library has access to O'Reilly or similar — tons of technical content there.

The official candidate guide is something a lot of people skip but it literally tells you the topic weighting and domain breakdown. It's the roadmap for your study plan. Never skip it.

I'll be honest, I wasn't sure I'd have time for this with two kids and a full-time shift schedule, but it worked out fine. I studied in chunks. Twenty minutes on my lunch break, maybe another half hour after everyone went to bed. PracticeTestGeeks was the thing that actually made it stick for me because I could pull up a few questions on my phone whenever I had a gap, and the explanations meant I wasn't just memorizing answers. I'd recommend going through their american welding society certification set more than once. First pass you'll bomb half of it. That's normal.

The trick for me was consistency over cramming. I didn't do marathon sessions because I just don't have those hours in my day, and honestly I retained way more doing a little every night. If you work full time don't stress about the people who say they studied 8 hours a day. You don't need that. Show up for twenty minutes, keep at it, and it adds up faster than you'd think.

I'll throw in my two cents since I just got through the AWS cert while working full time. PracticeTestGeeks was honestly the thing that kept me on track. I didn't have big chunks of time to study, so I'd do a handful of questions on my phone during lunch or right before bed. The explanations are what made it click for me. When I got something wrong it actually told me why instead of just flagging it, so I wasn't sitting there confused.

My advice if you're busy like I was, don't try to cram. Little and often beat the weekends where I told myself I'd study for four hours and then did maybe forty minutes. I'd run a short practice set every day, even just ten or fifteen questions, and over a couple months it added up. The welding symbols and the code stuff took me the longest, so I hit those areas extra. You'll find your weak spots fast once you start doing the practice tests. Stick with it and it's very doable around a job.
