Retaking courses to boost GPA can be beneficial, especially if it leads to a better job prospect in industries that prioritize GPA on resumes. While understanding the material is important, improving GPA through retakes can significantly impact future opportunities, particularly for graduate school applications. Some suggest that taking new electives related to the major might also enhance knowledge and GPA without the need to retake old courses. However, if the institution allows for grade replacement, retaking classes with lower grades may yield a more substantial GPA increase. Ultimately, the decision should consider both immediate GPA improvement and long-term career goals.
