 # BUGS
+- numeric interval deve converter respostas que usam virgulas para pontos decimais
 - a revisao do teste não mostra as imagens.
 - se aluno tem teste activo e é allowed uma segunda vez, deve manter o mesmo teste. adicionar opcao para eliminar um teste em curso.
 - melhorar o botao de autorizar (desliga-se), usar antes um botao?
