Diferentemente de v\u00e1rias institui\u00e7\u00f5es, a UFPR optou por substituir a tradicional reda\u00e7\u00e3o dissertativa-argumentativa longa (modelo ENEM,\u00a0Fuvest) por 5 propostas mais curtas por\u00e9m mais abrangentes quanto a tema, flexibilidade e conhecimento de mundo do candidato, tornando o exame mais seletivo<\/b><\/span><\/span><\/span><\/p>\n
