The answer to your question may depend on the specific rules and policies of your college or university. In general, if you have an E grade in a subject in all four semesters of your graduation, you may need to retake the exams for that subject to clear it.
Many colleges and universities have a minimum passing grade requirement for each subject, which may be a D or higher. If you have consistently received an E grade in a subject, it may indicate that you have not met the minimum passing requirements for that subject. In this case, you may need to retake the exams for that subject in order to clear it and graduate with a degree.
I would recommend checking with your college or university's academic advisor or registrar's office to get more information on their specific policies and procedures for dealing with E grades and retaking exams. They should be able to provide you with guidance on what steps you need to take to clear the E grade and graduate with your degree.
