How to prepare for the OMSB Selection Exam

What does the exam actually test?

150 single-best-answer questions in 2 hours 45 minutes, weighted Medicine 39%, Surgery 18%, Women's Health 13%, Emergency Medicine 12%, Public/Community Health 11%, Child Health 7%. [OMSB guide, §V–VI] Spend your time in roughly those proportions. The full blueprint is on the OMSB Selection Exam guide.

What kinds of questions come up?

OMSB names five angles: diagnosis, investigation, drug management, non-drug management and prevention. [OMSB guide, §VII] For each topic, revise all five, not only the diagnosis.

Step 1. How do I find my weak areas before I start?

Take a short diagnostic paper first, so you read where the gaps are instead of starting at page one of a textbook.

On OmanDoc this is the Subject Diagnostic: 20 questions in one subject, showing where to focus and what to read. The result is a reading map, not a grade. Without OmanDoc: time a mixed set of questions spread by blueprint weight, and note the domains below your average.

Step 2. What should I read, and from where?

Read the topic itself, from a source you can trust and cite. Each OmanDoc topic note is written from the course material and carries the page it came from — see the curriculum, in 20 categories mapped to the OMSB blueprint.

Which textbooks does OMSB suggest?

OMSB's guide lists general-practice references such as the Oxford Handbook of General Practice and John Murtagh's General Practice, with the British National Formulary and the Ministry of Health manuals. [OMSB guide, §VIII] The full list is on the exam guide page.

Why does the source page matter?

Knowing that an answer is right is half the work; knowing why, and where it is written, is what keeps it. Check every answer against the page that settles it.

Step 3. How do I practise questions properly?

Practise by category, check every answer against its source straight away, and keep the ones you miss.

Study Mode on OmanDoc: choose an option and the verdict comes back at once, right or wrong, with the page that proves it.

What should I do with questions I get wrong?

The Mistake Book keeps every question you missed, with the source page that settles it, until you get it right. The habit: read tonight what you missed today.

How many questions should I do?

Enough to cover every category in proportion to its weight, then repeat the ones you missed. OmanDoc's bank has 1,413 questions across 20 categories.

Step 4. How do I keep a plan that adapts?

Re-rank your subjects each week by how you performed, and put the weakest first. On OmanDoc, Performance shows what moved and what did not, and the plan reorders to put your weakest subjects first. If neurology is your lowest category this week, it goes to the top of next week's reading.

Step 5. When should I start timed mock exams?

Once every domain has had at least one pass, sit full timed papers under exam conditions: 150 questions in 2 hours 45 minutes. [OMSB guide, §V] That is 165 minutes for 150 questions, about 66 seconds each.

OmanDoc's Mock Exam is a full paper weighted like the real one, timed from the first question to the last. After each paper, misses go to the Mistake Book and the plan reorders — back to Step 2.

How long should I prepare for?

It depends on your starting gaps, which is why the diagnostic comes first. Three ways to plan it:

• About 12 months: start early and run the whole loop twice.
• About 4 months: one full pass of every category, then mock papers.
• About 1 month: a final month on your weakest categories and on mock papers.

Where do the exam dates come in?

Work back from the sitting date. The 2026 sitting ran on eight days between 1 and 16 September 2026. [OMSB guide, §IV] The next dates are not published yet; see the exam guide page.

Common mistakes to avoid

• Reading textbooks cover to cover before testing yourself.
• Ignoring the smaller domains: Child Health at 7% still counts.
• Relying on unverified material instead of sourced notes.
• Checking only whether you were right, not why.
