Is it fine if I claim extracurricular activities in my bachelor's degree even if I do not have proper certifications for them for a Master's?

Yes, you can include extracurricular activities from your bachelor's degree in your master's application even without formal certificates. Admissions committees value these experiences for the skills and qualities they demonstrate.

When listing these activities, clearly describe your role, responsibilities, and any achievements. Specific examples - such as organizing events or leading initiatives - help showcase your involvement, even if you don't have official documentation.
