  • Preparing for the ASE Exam: The ASE T1 exam tests knowledge in specific areas like engine repair, cooling systems, lubrication systems, and more. Lecturers need to prepare students for these exams by focusing on these key areas, providing study materials, practice tests, and tips on test-taking strategies.
