Free DHA Community & Public Health Medicine mock test
12 original exam-style questions from our Community & Public Health Medicine bank, timed at the exam’s own pace, scored against the 65% DHA pass mark. They span 8 of the 8 blueprint domains, so you will see exactly where you are weakest - free, no sign-up.
Sit 12 original exam-style questions at real exam pace
These are 12 original questions taken from our Community & Public Health Medicine bank, spread across 8 of the 8 domains of the published blueprint. You get 72 seconds per question, which is exactly the pace of the real SCO6012 exam (14 minutes for 12). At the end you will see which domains you are weakest in, and the full worked reasoning for every question.

A short diagnostic cannot predict whether you will pass - only the real exam does that. It will show you, honestly, where you currently stand.
What the real Community & Public Health Medicine licensing exam looks like
Candidates for a Community & Public Health Medicine licence in the UAE sit a computer-based multiple-choice examination - DHA exam code SCO6012, delivered through Prometric for DHA, MOHAP and SHA, and through Pearson VUE for DOH Abu Dhabi. The DHA pass mark is 65% (DHA CBT Guideline, Sep 2026); other authorities set their own, so confirm yours before booking. The result is reported to you as pass or fail only - your score is never released.
Pass marks at a glance: DHA exam codes and pass marks for all written exams in one sourced table.
The paper is built to a published blueprint, which is why a domain-by-domain diagnostic is more useful than a raw percentage. Your questions above were drawn from across Biostatistics, Communicable Disease Control, Environmental and Occupational Health, Epidemiology and Research Methods and 4 more - the same areas the real paper weights.
Before you can book the exam at all you need Dataflow primary source verification of your degree, licence and experience, which typically runs several weeks. Candidates routinely underestimate this and end up sitting the exam sooner after study than they planned. Check where you stand with our free eligibility checker or confirm whether your title even requires an exam using the Prometric exam checker.
You get three attempts in total across all UAE authorities - not three each - under the Unified Professional Qualification Requirements. At roughly AED 1,030 per attempt, plus the licensing delay each failure adds to your visa and start date, the cost of going in underprepared is not really the exam fee.
What is on the Community & Public Health Medicine exam: the full blueprint

Figures for the DHA exam, from the DHA CBT Guideline, Sep 2026. DOH, MOHAP, SCFHS, QCHP, NHRA and OMSB set their own length, timing and pass mark. See the DHA exam guide and pass marks for every DHA exam.
A worked Community & Public Health Medicine exam question
Every question in the diagnostic and in the paid bank is written to this standard: a clinical stem, four plausible options and the reasoning for the answer, with its source.
Biostatistics
Researchers compare mean systolic blood pressure among three independent diet groups. The data are normally distributed. Which test is most appropriate?
- APaired t-test
- BOne-way ANOVACorrect
- CChi-square test
- DMann-Whitney U test
Why: One-way ANOVA compares means of three or more independent groups with normally distributed data. A paired t-test compares two related measurements and the chi-square test is for categorical data.

Community & Public Health Medicine sample questions with answers
4 more original exam-style Community & Public Health Medicine questions, worked in full. They are not real or recalled exam questions, and none of them is in the diagnostic above, so sit that first if you have not.
Question 1 · Biostatistics
In a trial, stroke occurred in 20% of controls and 15% of treated patients over 5 years. How many patients must be treated for 5 years to prevent one stroke?
- A5
- B25
- C20
- D4
Show answer and explanation
Correct answer: C. 20
The absolute risk reduction is 20% - 15% = 5%, and NNT = 1/0.05 = 20. The figure 25 comes from the relative risk reduction (5/20 = 25%), which is not used to calculate NNT.
Reference: Straus, Evidence-Based Medicine, 5th ed.
Question 2 · Communicable Disease Control
Ten primary cases occur in households containing 50 people in total, including the primary cases. All contacts are susceptible. Within one incubation period, 8 more people fall ill. What is the secondary attack rate?
- A16%
- B36%
- C25%
- D20%
Show answer and explanation
Correct answer: D. 20%
The secondary attack rate uses susceptible contacts as the denominator, excluding primary cases: 8/(50 - 10) = 20%. Dividing by all 50 household members (16%) wrongly includes the primary cases.
Reference: CDC Principles of Epidemiology in Public Health Practice, 3rd ed.
Question 3 · Communicable Disease Control
A disease has a basic reproduction number of 4. Assuming homogeneous mixing and a fully protective vaccine, what minimum population immunity interrupts transmission?
- A25%
- B80%
- C75%
- D95%
Show answer and explanation
Correct answer: C. 75%
The herd immunity threshold is 1 - 1/R0 = 1 - 1/4 = 75%. The figure 25% is 1/R0 itself, not the proportion that must be immune.
Reference: Fine P, et al. Herd immunity: a rough guide. Clin Infect Dis 2011
Question 4 · Environmental and Occupational Health
On a summer afternoon, a construction worker collapses and is confused, with a core temperature of 41.2 C. What is the most important immediate action at the site?
- AGive oral paracetamol and observe
- BStart whole-body cooling at once
- CTransport first and cool in hospital
- DGive oral rehydration salts in shade
Show answer and explanation
Correct answer: B. Start whole-body cooling at once
Heat stroke needs immediate whole-body cooling on site; cold-water immersion cools fastest and is linked to survival. Antipyretics do not work because the raised temperature is not caused by a change in the hypothalamic set point.

How to use this diagnostic properly
- 1Sit it cold, once. Do not look anything up. A diagnostic you help yourself through tells you nothing. The number you get is only useful if it is honest.
- 2Read every rationale - especially the ones you got right. Getting a question right by elimination is not the same as knowing it. The worked reasoning is free above, whether or not you buy anything.
- 3Work weakest domain first. The breakdown orders your domains worst-first for exactly this reason. Studying what you are already good at feels productive and moves nothing.
- 4Re-sit under full exam conditions later. The real paper is far longer than this and stamina matters. Full-length timed papers are what the paid bank is for.
