Retaking a course after receiving a low grade can positively impact a graduate application, especially if the student improves significantly, such as moving from a D to an A. This demonstrates learning and growth. However, a marginal improvement, like a D to a C-, may not enhance the application. Students facing tough semesters, particularly in rigorous programs like Engineering Physics, should focus on managing their course loads effectively. Dropping a class without penalty and retaking it later can be a viable option, especially if it allows for better focus on future courses. Graduate admissions often prioritize self-motivation and the ability to learn independently over merely achieving high GPAs. Therefore, excelling in subsequent courses that build on the material may suffice without needing to retake the class.
