Professional data recovery, taught level by level. Each level draws a real case at random from a large bank, so you cannot memorise a position or an answer. Read the case, decide the correct steps yourself, and learn the mistakes that lose data. Finish the course and pass the field exam to earn your certificate.
Each chapter is a kind of rescue. Clear its levels to unlock the next. Every level pulls a random case from its bank, and a miss serves a fresh one. Clear them all, then sit the final field exam.
Unlocks when every chapter is cleared. A proctored sitting of 50 questions drawn from across every chapter. You need 40 of 50 correct to pass.
Type your name to put it on the certificate, then generate it.
Paste the certificate payload (the text encoded in the QR, or the line printed on the certificate record). The tool recomputes the SHA-256 integrity code and checks it against the code in the payload.
Honest note: the salt used in the hash is inside this page, so a determined person could recompute a code for altered details. The check confirms that a payload has not been changed since it was issued by this page. It is an integrity check, not a tamper-proof seal.
