Right now, in Portugal and in other places like the US, our schools are lowering the bar (making tests easier) to have a higher percentage of students with passing grades.
This is wrong because the only thing that its raising is the bar of mediocrity.
Tests should be hard not because we like failing grades and angry students but because hard tests force students to evolve their reasoning and deductive skills, memory, and a lot other brain activities.
Já aqui tinha escrito sobre os exames deste ano terem sido bastante fáceis, mas recomendo vivamente lerem este post do Pedro Melo, e as razões porque diminuir a dificuldade dos exames não é de todo uma boa ideia.
