Yes, retaking a class can often replace the original grade in college. Many institutions allow students to retake a course to improve their understanding and GPA. The new grade typically replaces the previous one in the GPA calculation, offering an opportunity for redemption. However, policies may vary, and some colleges may average the grades or have restrictions on the number of times a course can be retaken. It’s essential to familiarize yourself with your college’s specific policies on retaking classes to make informed decisions about improving your academic record.
