About this exam

The ERES Bonaerense in Medicina is the competitive residency entrance examination used in the Province of Buenos Aires to allocate places in hospital-based medical residency programs. It is aimed at physicians who have completed their medical degree and are seeking a first or subsequent residency post in the Buenos Aires provincial health system. The exam is a multiple-choice instrument that samples across the major clinical and non-clinical domains of undergraduate and internship-level medicine, including internal medicine, surgery, pediatrics, obstetrics and gynecology, emergency medicine, public health, pharmacology, semiology and imaging, and the legal-ethical foundations of practice. Preparation is best built around a structured review of each domain using standard Argentine and international references, followed by extensive practice with clinical vignettes that require you to reason from presentation to diagnosis and first-line management. Because the exam rewards breadth over depth, candidates who over-invest in a single specialty often lose ground; a balanced rotation across domains, with spaced repetition of high-yield topics and timed practice sets, tends to be more effective. The official provincial body publishes the current call, format details, dates, fees and scoring rules on its website, and candidates should treat that site as the authoritative source for all administrative matters.

What you'll study

Common questions

About ERES Bonaerense Medicina preparation

What is the format of the exam?

It is a multiple-choice examination delivered in a single sitting, with clinical vignettes and single-best-answer items spanning all listed domains. The exact number of items, time allowed and scoring method are set for each call by the provincial authorities; check the official body's website for the current specifications rather than relying on past cycles.

How difficult is it?

It is competitive rather than merely pass/fail: your score determines which places you can access, so the effective difficulty depends on the cohort applying in your year and the popularity of the programs you want. Most candidates find the breadth demanding, since questions move rapidly between specialties with little context switching time.

Can I retake the exam if I do not get a place?

Retake rules, eligibility windows and any limits on attempts are established by the provincial authorities for each call and can change between cycles. Confirm the current policy on the official site before planning a second attempt, and keep your documentation in order so a retake is not delayed by administrative issues.

How should I order my study?

Start with the highest-weight domains, internal medicine and the clinical specialties, then layer in public health, pharmacology and the legal-ethical content, which are easier to consolidate late. Build a weekly schedule that touches every domain rather than finishing one before starting the next, and reserve the final weeks for timed mixed practice.

How much time do I need to prepare?

Most successful candidates report several months of consistent, structured study rather than a short intensive burst, because retention across ten domains requires spaced review. The right duration depends on how recently you finished your internship and how fresh your clinical rotations are; be honest about your baseline before setting a timeline.

What are the most common failure modes?

Neglecting low-weight domains entirely, memorizing facts without practicing vignette reasoning, and failing to simulate exam timing are the classic errors. Another frequent problem is misreading the question stem, particularly items asking for the next best step rather than the diagnosis. Practicing under time pressure corrects most of these.

Does the exam include image-based questions?

Some items may present clinical data in a format that requires interpretation, but you should prepare to answer every question from the text provided. Build skill in reading and interpreting described findings, and do not assume you will be shown a figure for any given item.

Where do I find dates, fees and venue information?

All administrative details, including registration windows, fees, venues and results, are published by the official provincial body on its website. Those figures change from cycle to cycle, so consult that source directly; do not rely on forums, older candidates' recollections or third-party summaries for anything that affects your registration.

Is this page affiliated with the official examination?

No. This is an independent study resource and is not endorsed by or connected to the provincial authority that administers the examination. Use it for preparation only, and verify every administrative and regulatory detail against the official source before acting on it.
