Questions and answers

Every answer quotes the official docs, links its source and is approved by a person.
Should I still study the official path?

Every fact quotes the official docs. Code, two AI models and a person check it.
Do I need an account?
Not for the diagnostic. Sign in to save progress and open lessons and practice.
What if I find a mistake?
Tap “Something off?”. A person reads every report, and a wrong item is pulled until it is fixed.
Can you promise I will pass?
No. We help you practice what the exam guide measures.
Is Checksum affiliated with AWS or Microsoft?
No. Checksum is independent.
What happens to my data?
