Use this plan only if you are actually preparing for COF-C02 before its remaining window closes. As of April 14, 2026, Snowflake’s current transition FAQ says the English COF-C02 exam remains available until May 14, 2026, and translated COF-C02 exams remain available until July 31, 2026. If your exam date is after those windows and you can change it, move to COF-C03.

What to do |
Why |
| 0-10 |
restate one Snowflake boundary |
keeps storage, compute, security, and sharing from collapsing together |
| 10-25 |
review one lesson and one confusion pair |
turns content into fast exam pickers |
| 25-45 |
solve one scenario without notes |
tests reasoning instead of recall only |
| 45-55 |
write one miss rule and one better rule |
creates reusable correction loops |
| 55-60 |
confirm one fact in Snowflake docs or the transition FAQ |
keeps version timing and product behavior grounded |
Best repair order for weak lanes
| If you are weakest in… |
Fix it in this order |
| architecture and objects |
chapter 1 -> glossary |
| roles, grants, and governance |
chapter 2 -> cheat sheet |
| slow-query and cost questions |
chapter 3 -> resources |
| loading and unloading choices |
chapter 4 -> chapter 5 |
| Time Travel, cloning, and sharing |
chapter 6 -> faq |
Booking signal
You are getting close when:
- you stop treating a warehouse like the place data lives
- roles, grants, and ownership no longer blur together
- query profile and pruning come to mind before “make the warehouse bigger”
- you can explain why clone, Time Travel, and secure sharing solve different problems
Final 72-hour plan
- reread the cheat sheet once for the fast pickers
- use the glossary only for terms that still blur together
- confirm your version timing in the faq and resources
- do one last pass through your weakest chapter
- if your exam is no longer inside the
COF-C02 window, switch to COF-C03
