Pre admission preparation

Hi All, I have started preparation for GMAT but now for me it is only possible to apply some Indian bschools next year from October an I guess I have enough of time for it. .so can you suggest some options which I can do parallely with my preparation to improve my profile for selection ? One idea came to my mind is should I pursue distance PGDiploma in CR/Marketing/InternationalBusiness  from Symbiosis or any other reputed college. . will that make my profile some what more effective  ?? Thanks in advance
