Anyone found good free BLOCKCHAIN study resources besides the obvious ones?

I actually failed the first time by a few points. Total gut punch. But passed on the second attempt with a comfortable margin.

What changed: I stopped trying to memorize answers and started actually understanding the material. Specifically on BLOCKCHAIN exam — I went back to basics and worked forward from first principles.

Also switched from reading to doing. Less time with the textbook, more time on practice questions with detailed answer explanations.

You've got this. The second attempt is always better because you know exactly what the exam is like.

Quick data point: I spent 8 weeks studying, 2-2 hours a day, and passed with a 78%.

The section on BLOCKCHAIN exam took me the longest to feel confident about. Eventually I just drilled practice questions until I could answer them without hesitation.

What testing center did you end up booking? Some of them have much shorter wait times than others right now.

Quick update: just cleared 84% on my most recent blockchain-developer practice set using blockchain developer smart contract development. Sitting for the real thing in 3 weeks. Feeling cautiously optimistic.

For anyone finding this later: blockchain-developer is passable with consistent effort even working full time. I studied 67 minutes a day for 11 weeks. The blockchain developer smart contract development kept me honest about my actual gaps.

Quick update since I posted a few weeks ago stressing about this -- finally broke 80% on a practice test yesterday, which honestly I didn't think would happen this fast. The blockchain fundamentals stuff clicked once I stopped trying to memorize everything and just kept running through the practice questions until the patterns made sense.

I'm aiming to sit the real exam in about three weeks. Nervous but I feel like I'm actually ready this time, not just hoping for the best. If you're in the middle of studying right now just keep drilling the practice tests, it's slow at first but it really does compound.

Just passed my Blockchain Developer cert last month so I'll share what actually clicked for me. The whitepapers. I know that sounds obvious but I mean actually reading the original Bitcoin and Ethereum whitepapers, not summaries of them. Most study materials explain what the concepts are but the whitepapers show you the reasoning behind the design decisions, and that's what the tricky exam questions are really testing.

The other thing that helped was building a tiny demo project, even just a basic smart contract I could deploy on a testnet. It doesn't need to be impressive. Once you've actually debugged why a transaction failed or why your gas estimate was off, the theoretical stuff stops feeling abstract. The practice tests here were great for identifying my weak spots but that hands-on piece is what made the answers stick.
