To clear the CISA exam in 2025, focus on the latest ISACA syllabus and study regularly using the official review manual and QAE (Questions, Answers & Explanations) database. Allocate 2–3 months for preparation, with extra attention on high-weight domains like Risk Management and Governance. Take practice exams, review weak areas, and manage your time effectively during the test. Consistency, understanding concepts—not memorizing—and regular revision are key to passing on your first attempt.
