Hardest questions on the Portuguese citizenship test prep

We looked at around 7,700 answers given in our free practice demo and asked one question: where do people go wrong? The top answer is not a medieval king or an obscure law, but how long the President of Portugal serves. The answer is five years, and more than half of all answers got it wrong.

If you are preparing for Portugal's citizenship test, this list is a shortcut: ten questions, the right answer, and the specific wrong answer that catches people. One thing to be clear about first: these are questions from our own practice bank, written around the subjects the law lists, not questions from an official exam paper. For what the law actually requires, see our guide to the 2026 citizenship test.

Which ten questions do people get wrong most often?

Percentages are rounded. Each question had between roughly 370 and 400 answers.

You can try these exact questions, with the same four options, in our free practice quiz. It takes a few minutes, and it is more useful to make the mistakes yourself before you read why they happen.

Why do so many people get the President's term wrong?

Because Portugal has two national elections on two different clocks, and people learn one of them. A parliament (the Assembly of the Republic) runs for four years. The President is elected for five, and cannot serve a third term in a row. If you remember “elections every four years”, you will apply the wrong clock to the President. Learn them as a pair: President five, parliament four.

The number of MPs works the same way. The Constitution sets a range — at least 180, at most 230 — and leaves the exact figure to the electoral law, which fixes it at 230: 226 elected in Portugal and four by Portuguese voters living abroad.

The “organs of sovereignty” question is different. Almost half of the answers are wrong, and the likely reason is not that people do not know what a town council is. The trap is the word NOT. The Constitution names exactly four organs of sovereignty: the President, the Assembly of the Republic, the Government and the courts. Municipal councils are local government, so they are the answer. Our guide to local government explains the difference.

Dates: why the wrong answer is usually a real date

Four of the ten questions ask for a year. In every case, the most tempting wrong option is a genuine date from Portuguese history — just not the one asked about. That is what makes these questions hard for someone who learned a list of years without the story behind them.

• The Constitution: 1976, not 1974. The Carnation Revolution was on 25 April 1974. The Constitution came two years later: approved on 2 April 1976 and in force from 25 April 1976.
• The EEC: 1986, not 1992. Portugal joined on 1 January 1986, on the same day as Spain. In 1992 the Maastricht Treaty created the European Union under that name, but Portugal was already a member. Our page on Portugal in the European Union sorts out the dates.
• The Republic: 1910, not 1926. The monarchy fell in the revolution of 5 October 1910. 1926 is the military coup that led to the dictatorship.

The practical lesson: for each date you learn, learn its neighbour too. If you can say “1974 is the revolution, 1976 is the Constitution”, the wrong option stops looking right.

The flag and the anthem

Nearly half of the answers about the castles are wrong, and the tempting option is easy to explain: five. Look at the shield in the middle of the flag. Inside it are five small blue shields, called quinas. Around them, on a red border, are seven golden castles. Answer five and you have remembered a real number from the flag, just not the right part of it.

The anthem is the easiest question on the list, and one in three still miss it. The Constitution says it in a single line: the national anthem is A Portuguesa. Grândola, Vila Morena is the song that signalled the 1974 revolution, which is exactly why it works so well as a decoy. Our guide to the national symbols covers the flag and the anthem in more depth.

When the famous answer is the wrong one

Fernando Pessoa is the Portuguese writer most people abroad have heard of, so he is the obvious pick for the Nobel Prize in Literature. He never won it. The Portuguese laureate is José Saramago, in 1998. It is a good rule for the whole test: the best-known option is not automatically the right one.

Compulsory schooling catches four answers in ten, and 16 is the tempting wrong option. In Portugal, the law treats children and young people from 6 to 18 as of school age. The obligation ends when the student finishes secondary school or, without a diploma, in the school year in which they turn 18.

Where these numbers come from

Our quiz records each answer: which question, which option, right or wrong. Only totals appear here, nothing about any individual. Between 19 July and 11 October 2026, people took the free 20-question demo about 400 times, giving roughly 7,700 answers. We only counted a question if it had at least 30 answers.

The practice and full mock modes were left out because no question there reached that threshold yet, so these figures describe the demo's 20 questions, not our whole bank. One day in September had an unusual spike of attempts; without it, the order of the list stays the same and no percentage moves by more than five points.

How to use this list

Treat it as a checklist rather than something to memorise. For each question you got wrong, ask what the option you chose actually is. Knowing that four years is a parliament and 1992 is Maastricht will help you however the official question ends up being worded.
