How to Use Domain Weights in Your Study Plan
The heaviest domain on the KCNA is "Kubernetes Fundamentals" at null%. Start here and return to it regularly.
Allocate study time proportional to domain weight — a 25% domain deserves roughly 25% of your prep hours.
Never skip a low-weight domain. A 10% domain still represents 5–7 exam questions — enough to make the difference between pass and fail.
Use JT Exams domain analytics to track your accuracy per domain automatically. The system routes extra questions to your weak areas.
