Common pitfalls

The three traps that kill CS0-003 candidates: (1) over-memorizing acronyms instead of practicing the application of concepts in scenarios, when the exam is scenario-driven, not a vocab quiz. (2) Skipping the heaviest-weighted domain because it feels less interesting, which can fail the whole exam by neglecting Security Operations. (3) Not timing practice sessions, when the exam has a real clock and pacing is its own skill. Build timing into your last two weeks of prep.
