SnowPro Core Prep is a free study application for the Snowflake SnowPro Core (COF-C03) certification. It exists because the alternatives were a paywalled question bank you cannot inspect, or a folder of notes with no way to test yourself against them.
This is a personal project maintained by one person. There is no company behind it, no team, and no support desk — which is stated here so expectations are set correctly rather than discovered later. Email reaches a real person and is usually answered within a few days.
There is none. The service is free, carries no advertising, has no paid tier, and collects no payment details. It is not funded by selling or sharing your data — see Privacy, which describes exactly what happens to it.
Every note and every practice question is original work, written independently and checked against Snowflake's publicly available exam guide and documentation. None of it is taken from a real exam. It reflects the author's own understanding, and where that understanding is wrong the fastest way to fix it is to say so — corrections are welcome at the address above.
