Finally passed my blockchain crypto certification after three attempts — here's what worked

Okay so I've been lurking on this forum for months and I feel like I owe it to everyone who helped me to actually post my experience. I failed the blockchain crypto exam twice before I finally passed last week with a 78%. The first two attempts I was just reading through the official materials and thinking that was enough — it absolutely is not.

What finally clicked for me was grinding through a solid BLOCKCHAIN CRYPTO practice test set consistently for about 3 weeks, like 45 minutes every morning before work. I'd been weak on consensus mechanisms and smart contract vulnerabilities, which kept tanking my score. The study guide I was using before didn't go deep enough on DeFi protocols and Layer 2 scaling — huge mistake.

For anyone currently prepping, my exam tips: don't underestimate the cryptography fundamentals section, it's about 22% of the exam and way more math-heavy than the prep materials suggest. What resources is everyone else using? Would love to compare notes.
