COF-C02 · 50 days · 8 weeks
The Curriculum

50 days.
5 domains.
One pass on COF-C02.

A structured daily series taking you from Snowflake basics to exam-ready. Built by a working data engineer, not a course factory. Every concept day ships a topic breakdown, a hands-on lab, an exam-tip cheat sheet, and 5 practice questions mapped to the official exam guide.

01 / What lands in your inbox

Every concept day follows the same structure. No fluff, no filler — just the parts that move the needle on exam day.

01

Concept, explained

The day’s topic broken into 2–4 short sections with diagrams and runnable SQL. Built to read in one coffee.

02

Hands-on lab

Copy-paste SQL you can run on a free Snowflake trial. Every lab includes setup, demo, and cleanup.

03

Exam tip box

The “watch for this on the exam” callouts. Common traps, edge cases, and answer-pattern shortcuts.

04

5 practice questions

Single and multi-select, with explanations. Mapped to the same domain weighting as the real exam.

02 / The full 50-day map

Eight weeks. Five domains, mid-week reviews where the topics demand them, and a Weekly Practice Test at the end of every week to lock in what you just learned.

Why this isn’t another course dump

Most SnowPro material is either a 12-hour video you’ll never finish or a thousand-question dump with no context. This series is a daily habit designed for working engineers studying in 30-minute windows.

You won’t memorize trivia. You’ll understand why Snowflake makes the choices it does — which is exactly how the exam tests you.

  • Domain-weighted, not topic-dumped Each week mirrors the COF-C02 exam guide weighting so you spend more time where the points are.
  • Live-verified against Snowflake docs Every limit, default, and edition note is checked against current Snowflake documentation — not pulled from outdated training data.
  • Built by a practitioner Written by a working data engineer, not a content team. Exam-tip patterns come from actual gotchas, not generic flashcards.
  • Real labs, not pseudo-code Every concept day’s SQL runs end-to-end on a free Snowflake trial. Setup → demo → cleanup, no residue.
