This is awful advice.
Going to a carib school with poor grades and a sub par MCAT on multiple attempts is paramount to setting your money on fire.
meh if he wants it he can gamble, thousands do it....might not get the outcome he wants but if you really really want the MD, with those stats your best bet is going Carib
and let's not forget that some of those Carib grads do actually end up matching in Canada or USA. it would take so much effort for a 20 MCAT but I mean there is that slight possibility
