How to study smart
Focus on knowing WHEN to use each service, not just what it does. The exam tests judgment, not memorization.
The four domain weights are your study budget. Spend 30% of your time on Secure, 26% on Resilient, and so on.
SQS vs SNS vs EventBridge is a frequent question cluster. Know the difference cold.
For storage questions: S3 vs EFS vs EBS vs FSx. Map each to its use case before exam day.
Understand VPC deeply — subnets, route tables, Internet Gateways, NAT Gateways, and VPC Peering appear constantly.

FAQ
Most people with some AWS exposure take 4–8 weeks of consistent study. Complete beginners typically need 2–3 months. Daily 20-minute spaced repetition sessions compound faster than weekend cramming.
Yes. Free accounts get access to a curated set of questions across all four domains immediately — no credit card required. Upgrade to Pro when you're ready for the full question bank and timed mock exams.
No. Real exam questions are under strict NDA. Every question in Kalleo is original, written by practitioners who have passed the exam, targeting the exact concepts and decision patterns the test covers.
Those are question dumps. Kalleo uses spaced repetition — the SM-2 algorithm surfaces each card right before you'd forget it. You learn faster, retain longer, and build real recall rather than pattern-matching.
Consistently scoring 80%+ on Kalleo mock exams strongly correlates with passing. The real exam is slightly harder, so give yourself a buffer above the 72% passing threshold.
