An MBA is a better (much better) option than an M.Sc. Because:
(1) It has more marketability better jobs
(2) Larger alumni network better resources
(3) More flexibility. For e.g. several top schools such as Harvard, Stanford, Yale etc. Allow applicants to apply during their final year. A school such as ISB allows applicants to apply either during undergraduate programme, with less than 2 years of work experience or with more than 2 years of work experience. This literally makes an M.Sc. Or an MiM a redundant degree. Hope this helps.
