I have been trying for a good GMAT score but unfortunately, i am still stuck in mid 500s.

I am not sure whether i should stick with GMAT and apply for regular MBA or i should switch to EA and try my luck.

I am looking for Canadian, European and Indian B-schools. Below are the colleges i am looking after -

Smith School of Business
