caseSQL Pro · Launching soon
On top of the 100 free missions, Pro adds 10 interview-tagged missions from companies that ask these questions (Stripe, Google, Amazon, and 7 more), verifiable path completion certificates you can link on LinkedIn, and a personal analytics dashboard that tells you exactly which concepts to drill next.
$12/mo or $99/year when it launches. Free tier stays free forever — Pro is additive.
Pillar 1 · Interview prep
Each Pro mission is framed as a hiring-manager prompt from a specific company, with a full written walkthrough covering the idiomatic solution, one common wrong approach, and the judgment call interviewers listen for. No multiple-choice. No “pick the right aggregate function” drills. The same shape of question you'll see on the panel.

Question archetypes drilled
Pillar 2 · Career-readiness
Finishing a path unlocks a verifiable completion certificate with a share URL you can put on LinkedIn. Your analytics dashboard shows where you're strongest — and specifically which SQL concepts you're still reaching for hints on.

SAMPLE01
Every certificate has a public verify URL — casesql.com/verify/[code]— that shows the holder's name, path, and completion date. No email or internal IDs are ever leaked.
On your profile, Pro users see 5 charts that answer the questions a serious learner actually asks:
The weakest-concepts chart ranks the SQL topics where you've needed the most hints — so instead of guessing what to practice, you know.

No. The 100 existing missions, the 5-tier validator, and all hints stay free forever. Pro is additive — net-new interview missions, certificates, analytics — never a paywall on content that used to be free.
Learners actively interviewing for data/analytics roles and mid-career analysts who have finished a path and want more depth. If you're brand-new to SQL, start with the free tier — the fundamentals are all there.
Yes. Monthly plans cancel at the end of the current billing month. Annual plans are pro-rated. No retention emails, no dark patterns.
