About this exam

EFOMM is the entrance examination for the Escola de Formação de Oficiais da Marinha Mercante, Brazil's merchant marine officer training school. Passing it is the first step toward a career as a deck officer or engineering officer aboard merchant vessels. Candidates are typically high-school graduates or students in their final year who are comfortable with a demanding, multi-subject syllabus and with the discipline of a maritime career. The exam spans mathematics, physics, chemistry, Portuguese language and literature, English, an essay, and general knowledge, so it rewards broad competence rather than a single specialty. Preparation usually means working through the full syllabus systematically, prioritizing mathematics and physics because they carry heavy weight and underpin later coursework, then building Portuguese and English through steady reading and writing practice. A realistic study plan mixes theory review with timed problem sets and regular essay writing, and leaves room for revisiting weak topics.

What you'll study

Common questions

About EFOMM preparation

What exactly is EFOMM?

It is the competitive entrance exam for the merchant marine officer training school. It selects candidates for officer training in the deck and engineering branches. The exam is academic, covering several high-school subjects plus an essay, and it is administered on fixed dates announced by the official body.

Do I need to be affiliated with the Navy to apply?

No. It is an open competitive examination. Candidates must meet the eligibility conditions in the current official announcement, which typically concern age, completed or ongoing secondary education, and physical and documentary requirements. Read that announcement carefully, since eligibility rules change between editions.

How hard is the exam?

It is genuinely demanding: the syllabus is broad, the mathematics and physics problems require real reasoning rather than recall, and the essay is scored on argumentation and written standard. Candidates who treat it as a sprint usually struggle. Those who prepare over many months with timed practice tend to do better.

How many questions are there and how long is the exam?

The official body publishes the current structure, question count, and duration in each edition's announcement, so check its site rather than relying on older material. Because these details can change, plan your practice around the subjects and question styles rather than a fixed count.

Can I retake the exam if I fail?

Retake rules are set by the official announcement and may depend on eligibility conditions such as age. Consult the current notice for the authoritative answer. In practice, many candidates sit the exam more than once, and a first attempt is often best treated as diagnostic experience.

In what order should I study the subjects?

Start with mathematics and physics because they carry the most weight and take longest to build, and keep Portuguese and English running continuously through reading and short writing tasks. Add chemistry and general knowledge in parallel blocks. Revisit weak topics on a fixed cycle instead of finishing one subject completely before starting another.

What are the most common ways candidates lose points?

Running out of time on quantitative sections, skipping units and significant figures, writing an essay that summarizes instead of arguing, and neglecting English reading speed. Another frequent problem is studying only familiar topics. Simulating full exams under time pressure exposes these weaknesses early enough to fix them.

How should I prepare for the essay?

Write regularly under time limits and get feedback on structure, thesis clarity, cohesion, and command of written standard. Build a small bank of current-affairs themes you can discuss with concrete examples. Practice planning for a few minutes before writing, since a clear outline usually raises the score more than extra length.

Where do I find official dates, fees, and results?

Only the responsible official body publishes authoritative information on registration windows, fees, exam dates, and results. This page is an independent study resource and does not administer the exam. Always confirm logistics on the official site before making travel or payment decisions.

Is English or Portuguese more important for a maritime career?

Both matter. English is the working language of international shipping, used in bridge communications and documentation, while Portuguese is essential for the exam essay and for study in Brazil. Treat them as long-term skills: daily reading in both languages pays off in the exam and later at sea.
