Progress deliberately. Complete one → absorb feedback → tackle the next one. You’re building skills, not collecting completions. Start here: 🔗 codehawks.cyfrin.io/first-flights
Read the feedback. Don’t just check your score. Study what you missed and why. Look at severity classifications. Use what you learn to inform your next attempt. Keep missing the same vulnerability type? That’s your signal to review it.
