How to study effectively

01
Start with scientific concepts
Infection control and chemistry questions appear consistently across all state versions. Master these first — they also reinforce hair and skin content.
02
Use timed practice
Most students who fail do so from running out of time, not lack of knowledge. Practice with a timer to build exam-day pacing and reduce anxiety.
03
Review your weak domains
After a practice test, check your domain breakdown. Spend focused study time on domains below 70% before your exam date.
