Typically, you would only need to reappear for the practical exam. Since you've already appeared and presumably passed the internal and theory exams, you should not be required to retake those.

However, it's crucial to check your university or college's specific rules and regulations. There might be particular circumstances or guidelines related to practical exam absences and re-appearances.

To get accurate information, contact your university's examination department or your department's academic advisor. They can provide specific guidance based on your situation and the institute's rules.

Remember, every institution has its own policies, so it's essential to verify the information from the appropriate source.

hope this helps you!!
