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.
Issued to your account name. Generate it to see the certificate.
Paste the certificate's code (the text under the QR, or the line printed on the certificate record) or its verification link. The server looks it up and confirms it against the account record that issued it.
The check is a real server lookup, not a client-side computation: a code is valid only if a matching, unrevoked certificate record exists and recomputes under the server's own signing key.
