Hello,

The eligibility criteria to pursue msc in international business is to have 50% marks in bachelor of commerce undergraduate degree and the admission process to get into good college is through CAT/XAT/GMAT.

However, there are some universities which will allow a science graduate to pursue msc in international business but you need to crack above listed exams for entrance and lot of hardwork is also required to gain basic knowledge of commerce subjects.

Talking about relativity, both are completely different fields with varying job profiles.

Good luck!
