Assessing your strengths and weaknesses for the ACT starts with taking a diagnostic practice test under timed conditions to simulate the real exam. Afterward, review your results carefully to identify which sections and question types you handle well and which ones consistently challenge you. Break down each section—English, Math, Reading, Science, and Writing—analyzing patterns in your mistakes, such as careless errors, time management issues, or concept gaps. Keeping a study journal or tracker can help monitor progress over time and adjust your preparation plan accordingly. Understanding your strengths allows you to leverage them, while focusing on weaknesses ensures targeted practice that leads to more balanced improvement and higher overall scores.
