don't do that, it's a waste of time really. go get some relevant work experience, do pre-mfe prep courses online from quantnet or UCLA/UCB if necessary and ace them, basically try hard to make your portfolio better, then apply to tier1 schools when you're reday. Aim for a tier1 school, you have pretty quantitative/relevant educational background, so you have a decent shot. 加油!
你这个情况应该不太现实,why would a tier one school admit a student who already pocess a msfe degree?
试想一下,如果你把自己的情况,设想成拿了一个20名以外的mba,之后再去投前10的mba,why should they admit u?
千万不要gap,工作一年再申也比gap强
