RM and SM are different schools now and are no longer considered XIMB. XSRM and XSoS are now Xavier School of Rural Management and Xavier School of Sustainable Management respectively. 

• The RM and SM programs come under Xavier University, Bhuvaneshwar. This means that post the convocation, your degree would read “XUB” and not “XIMB”. But you would be happy to know that the faculty is the same and placements are deserving. 
• You would be exposed to diverse sectors regardless of what course you are pursuing. 
• If RM and SM are the only specializations for you, it’s then up to you to choose whatever future you would like. Agricultural finance and GIS tagging are some sectors that are in trend these days in the line of either specialization. 

Both the courses are equally good and have their own importance. So, it’s all your decision, which field you want to pursue your career in.
