Mock tests play a crucial role in ACT preparation by simulating real exam conditions and helping students gauge their readiness. They allow you to practice timing, pacing, and stamina, giving a realistic sense of how to manage all sections within the allotted time. Taking regular mock tests also helps identify strengths and weaknesses, reveals common mistakes, and highlights areas that need more focused study. Reviewing answers afterward ensures that lessons from errors are applied, gradually improving accuracy and strategy. By incorporating mock tests into a structured study plan, students can build confidence, reduce test-day anxiety, and enhance overall performance on the ACT.
