Might there be a way to study for the Portuguese proficiency test required for obtaining Portuguese Citizenship? Or put another way, would there be a way to measure proficiency level to feel confident about taking the test?
I found a number of practice exams provided by the Center for Evaluation and Portuguese Certification Foreign Language (CAPLE) right here : http://caple.letras.ulisboa.pt/pages/view/27 .
It includes practice CIPLE exams, which a number of members have taken or are preparing to take. You can maybe follow that discussion here: CIPLE Exam, Anyone?
