How it works

From “am I ready?” to “I’m ready.”

One loop: practice, see where you stand, practice what matters.

  1. Step 1: Pick your certification

    Choose from 9 certifications across Databricks, dbt, Google Cloud, Snowflake, and Anthropic. Start with a free one.

    Explore certifications filtered to free: dbt, Google Cloud and SnowPro Core cards, each marked Free, with question and domain counts

  2. Step 2: Practice like it's exam day

    Timed mocks against the exam timer, quick practice that shows each answer as you go, and drills on any domain you choose.

    Practice question with the answer revealed: the correct option marked in green and the chosen wrong option in pink

  3. Step 3: Know exactly what's next

    Results rank your domains weakest first, and Progress tracks your accuracy by domain, so you know what to practice next.

    Timed mock result: 35 of 45 correct (78%) against an 85% passing score, with the weakest domain and a review-missed-questions next step
