The heaviest domain on the CS0-003 is "Security Operations" 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.
