How to get the most out of AI First Flights 🧵

Access to practice ≠ practicing effectively

Here’s how to actually level up your auditing skills 👇

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.

Progress deliberately. Complete one → absorb feedback → tackle the next one.

You’re building skills, not collecting completions.
