What are the chances of an elementary graduate to be successful

Not really zero...sometimes inability to complete an education does not mean inability to perform one's given talent, most of the cases was due to the person's financial incapability. There were people who may not have earned education, however they were given ingenuity that brought them success and progress... I would say not zero, but slim.

yes man you are very correct.graduate doenot make a lot of sence.but actually the qualities you have make the real differnce
