Yes, with a B.Sc. in Life Sciences, you can definitely pursue an M.Sc. in Nutrition! This is a good path, as your background in life sciences provides a strong foundation for understanding the biological and chemical processes involved in nutrition.

Many universities conduct their own entrance exams for postgraduate programs, including M.Sc. in Nutrition. These exams might focus on general aptitude, subject-specific knowledge of nutrition or life sciences, and research skills. Check the websites of the universities you're interested in for details about their specific entrance exams and eligibility criteria.

Some universities might consider scores from national-level entrance exams for postgraduate programs in life sciences or biotechnology.

Graduate Aptitude Test in Biotechnology (GAT-B): This exam is conducted by the Bioinformatics Unit (DBT-BUILD) of Department of Biotechnology (DBT), Government of India. While primarily focused on biotechnology, it might be relevant for universities with a strong focus on the scientific aspects of nutrition.

National Entrance Test (NET) in Life Sciences: Conducted by the University Grants Commission (UGC), this exam is for eligibility for lectureships and research fellowships in Indian universities and colleges. While not the primary purpose, some universities might consider NET scores for M.Sc. programs in related fields like nutrition.
