Acredito que para fazer essa prova, seja necessário ao menos 200 horas de estudo. Três horas por dia durante pouco mais de 2 meses e já se pode fazer a prova.
Ok, eu sei. Três horas pode parecer muito tempo, ainda mais para pessoas que trabalham, estudam e possuem amigos e família, como eu. Mas a grande sacada esta em aproveitar todos os momentos do dia...e fazer render o tempo.
Existem técnicas de estudos que tratam do aprimoramento do conhecimento e da capacidade das pessoas guardarem as informações que adquirem. Pretendo postar algo sobre isso em breve.


Em, breve também começo a pesquisa a respeito do primeiro item da prova.
