Since you have a strong background in Mathematics with a 9 CGPA, pursuing M.Sc. Electronics may not be the right choice as it requires strong physics knowledge, which you’re not comfortable with. Since you’re also not interested in teaching, B.Ed. won’t suit you either. Instead, you can explore options like M.Sc. Mathematics, Statistics, Data Science, or MCA, which align better with your skills and open careers in IT, finance, research, and analytics. Certifications in Data Science, AI, or MBA later can also give you good career opportunities.
