Mathematics remains one of the most challenging subjects for students, leading to significant struggles in academic achievement. Effective diagnosis and remedial teaching are crucial in addressing the learning gaps in mathematics, particularly for students facing difficulties in grasping key concepts. This paper explores the importance of diagnosing learning difficulties in mathematics and offers remedial teaching strategies that can help improve student performance. By identifying common areas where students struggle and providing tailored interventions, educators can help students overcome barriers to learning and develop stronger mathematical skills.
