Hi Product Hunt 👋 I built CertLand Radar because most cert prep tools have the same problem: they hand you a giant question bank and let you figure out what to study. That's backwards — you should know your gaps BEFORE you grind through 500 questions, not after. Radar runs a short diagnostic sample weighted to your exam's actual official domain breakdown (not just an even split across topics), scores you against that real weighting, and tells you which domains are actually weak — with a day-by-day study plan built from the result. It's free, no card, no signup required just to see your score. If you decide to go deeper, the Exam Pack ($14.90 one-time) unlocks the full curated question bank for that exam — every wrong answer is tagged with WHY it's wrong (not just "incorrect"), plus flashcards built from your own mistakes and an official-length mock exam with a go/no-go call before you book the real thing. Would love feedback: which certification should the next diagnostic cover?
