PSM for FMGE: Sure Shot 25+ Questions & High-Yield Topics | 2026

A 45-year-old man, a rural-district labourer in Rajasthan, has a non-healing ulcer on his foot. He does not have a history of diabetes. Upon examination, you observe loss of sensation in a glove-and-stocking pattern and thickened ulnar nerves on both sides. He is already enrolled in a National Health Program by the district surveillance team. Which program? What is the present elimination goal? This situation - and a dozen others of this kind - is precisely what Preventive and Social Medicine (PSM) hurls at you in FMGE.

QUICK ANSWER

Community Medicine or PSM (Preventive and Social Medicine) is the science of disease prevention, health promotion, and the health systems of populations. It is one of the subjects with the highest weight as it covers about 25-30 questions in the FMGE exam (out of 300). The areas of high yield are National Health Programs, Biostatistics (calculations of sensitivity/specificity), the National Immunization Schedule, and Epidemiological study designs. First mention: Textbook of Preventive and Social Medicine by Park (25th edition).

FMGE RELEVANCE

PSM is found in FMGE at high frequency - anticipate 25-30 direct questions. High-yield focus: Immunization Schedule, Epidemiological study designs, National Health Programs, Biostatistics formulas, and Screening test parameters. The focus of recent FMGE papers has been on application-based scenarios that include health program targets, Odds Ratio/relative risk calculations, and clinical vignettes related to vaccines.

What is PSM / Community Medicine?

Preventive and Social Medicine (PSM) is the subdivision of medicine that deals with disease prevention, life extension, and health promotion by organized community activities. In contrast to clinical medicine, where you work with one patient at a time, PSM works with populations - with whole districts, states, and nations.

Consider PSM as the operating system of healthcare in India. Clinical subjects are the apps; PSM is the platform on which they all run. I have encountered in clinical practice thousands of MBBS graduates who can diagnose pneumonia in a patient, but who cannot answer you the case fatality rate of pneumonia in children under five in India, or which National Health Program deals with it. It is that gap that FMGE tests.

The topic is a general one, encompassing Epidemiology, Biostatistics, Environmental Health, Nutrition, Occupational Health, National Health Programs, Demography, and Maternal & Child Health - each a separate cluster of questions in the exam.

Why PSM is Your Highest-Scoring FMGE Subject.

The biggest error foreign medical graduates make is treating PSM as a theoretical subject to be learned in the final week. Such a strategy backfires. PSM has about 25-30 marks in FMGE, ranking it alongside Medicine and Surgery in terms of raw questions.

The scoring advantage is actual. In contrast to Medicine, where one question may have three possible differential diagnoses and two inquiries, PSM questions tend to be direct recall - What is the case-finding tool in RNTCP? or What is the sensitivity formula? Know it, score. If you don't, you lose a free mark. I would tell students on the wards when they were doing community postings: "Every PSM question you lose is a gift you sent back unopened.

The topic is amenable to systematic preparation. The subjects are exhaustive, the facts are immutable, and the questions are patterns over the years. With a concentrated 10-12 days revision of PSM, you can reasonably expect to gain 20-25 marks to your overall, which can be the difference between 145 and 170.

National Health Programs - The 8-10 Guaranteed Questions.

The most predictable source of questions in PSMGE in FMGE is the National Health Programs. Out of this chapter alone, every sitting generates 8-10 questions. The trick is to be aware of the program name, the target disease, the strategy, and the target or elimination year.

The most common programs tested are:

National Tuberculosis Elimination Programme (NTEP) - formerly RNTCP. The goal of India is to eliminate TB by 2025 (in line with the National Strategic Plan). CBNAAT/TrueNat is the diagnostic backbone for initial diagnosis, replacing sputum microscopy as the primary tool. The daily fixed-dose combination (FDC) regimen is used; intermittent DOTS is no longer used. The NIKSHAY portal is the digital surveillance platform. This change from RNTCP to NTEP and from intermittent to daily therapy is the most frequently tested change in recent FMGE papers on the wards.

National Vector Borne Disease Control Programme (NVBDCP) includes Malaria, Dengue, Chikungunya, Kala-azar, Japanese Encephalitis (JE), and Lymphatic Filariasis. The exam is fond of queries concerning the targets of elimination: Kala-azar elimination target was 2020 (revised); Lymphatic Filariasis elimination targeted by 2027. Rapid Diagnostic Tests (RDTs) based on HRP-2 antigen detection for P. falciparum are a recurring query.

National AIDS Control Programme (NACP) - is in Phase V. Know the "Test and Treat" policy: any individual who tests HIV-positive is initiated on ART regardless of the CD4 count. Initial ART regimen: TLD (Tenofovir + Lamivudine + Dolutegravir). This drug combination is a crossover question with Pharmacology.

National Programme for Prevention and Control of Cancer, Diabetes, CVD and Stroke (NPCDCS) - the NCD program. Population-based screening at Health & Wellness Centres under Ayushman Bharat is the strategy in place. Screening targets: all individuals >30 years.

Biostatistics - Formulae Fetching Direct Marks

The second-highest yielding PSM chapter in FMGE is biostatistics, which provides 5-7 questions per paper. The positive news: these questions are formula-based. Learn the formula, use it right, and the mark is yours.

Basic equations that you should memorize:

Sensitivity = True Positives/ (True Positives/False Negatives) x 100. 

It responds: "How sensitive is the test to disease? A screening test must be very sensitive. Specificity = True Negatives / (True Negatives + False Positives) 100. It provides the answer to the question: "How good is the test in ruling out disease? A confirmatory test must be very specific.

• Positive Predictive Value (PPV) = TP / (TP + FP). 
• Negative Predictive Value (NPV) = TN/ (TN + FN). 

The exam trap: PPV and NPV are affected by prevalence, whereas Sensitivity and Specificity are not. This is a mistake that students tend to make - examiners are aware of it, and they are tested on it time and again.

Case-control studies use Odds Ratio (OR): OR = (a × d)/(b × c) of the conventional 2x2 table. Relative Risk (RR) is used in cohort studies: RR = [a/(a+b)] / [c/(c+d)]. Identifying the measure associated with a specific study design is a classic FMGE question.

Standard Error of Mean (SEM) = SD/sqrt (n). A p-value less than 0.05 indicates that the result is statistically significant. Type I error (alpha) = to reject a true null hypothesis. Type II error (beta) = false rejection of a null hypothesis. Power of a study = 1- beta.

During my teaching years, I have discovered that students who create a one-page formula sheet and update it three times prior to the exam can respond to Biostatistics questions in less than 30 seconds each. That pace liberates time for more challenging clinical queries.

Epidemiology - Study Designs & Disease Measures

FMGE epidemiology questions are pattern questions. The exam will assess your skills in recognizing study designs in clinical situations and using the appropriate measure of association.

Hierarchy of study designs (weakest to strongest evidence): Case report, Case series, Cross-sectional study, Case-control study, Cohort study, Randomised Controlled Trial (RCT), Systematic Review / Meta-analysis.

The highest-yield distinctions:

A case-control study begins with disease (cases) and looks back at past exposure. It calculates the Odds Ratio. A cohort study begins with exposure and follows participants forward in time to assess disease outcomes. It calculates the relative risk. This one difference - backwards vs. forward, OR vs. RR - creates 2-3 questions in almost every FMGE paper.

Incidence vs. Prevalence: Incidence measures the number of new cases over a given period. Prevalence is used to measure the number of existing cases at a specific point in time (point prevalence) or over a period of time. The relationship: Prevalence = Incidence x Duration. In the case of a long-term disease (e.g., diabetes), prevalence is significantly greater than incidence.

The incidence in outbreaks is the attack rate. Secondary Attack Rate (SAR) does not include the index case in the denominator - a repeated FMGE question.

According to the WHO's Epidemiology for Public Health framework, it is crucial that the public health decision-making process be informed by an understanding of these measures, and precisely this informed understanding is what FMGE tests.

Vaccines Made Simple: National Immunization Schedule.

The Indian National Immunization Schedule (Universal Immunization Programme (UIP)) is a guaranteed 3-5 question source. The trick is to be aware of the exact age of administration and route.

• Birth doses: BCG (intradermal, left upper arm), OPV-0 (oral), and Hepatitis B birth dose (intramuscular). 
• 6 weeks: OPV-1, Pentavalent-1 (DPT + HepB + Hib), fIPV-1 (fractional inactivated polio vaccine, intradermal), and Rotavirus-1. 
• 10 weeks: OPV-2, Pentavalent-2, Rotavirus-2. 
• 14 weeks: OPV-3, Pentavalent-3, fIPV-2, Rotavirus-3. 
• 9 months (9-12 months): Measles-Rubella (MR) first dose, Vitamin A first dose (1 lakh IU), and JE-1 (in endemic districts). 
• 16-24 months: DPT Booster-1, OPV Booster, MR second dose, JE-2 (endemic districts), Vitamin A second dose (2 lakh IU).

FMGE exam traps in vaccines: 

BCG is the only vaccine given intradermally in the routine schedule. The pentavalent vaccine has substituted the DPT + HepB + Hib with a single injection. 

The measles vaccine has been replaced by Measles-Rubella (MR) as a single vaccine in the country. In 2016, the rotavirus vaccine was launched and is given orally. 

The test usually includes the question: "What vaccine is not administered at birth? - and the answers to the question will challenge your knowledge of the specific list of birth-doses.

It can be remembered by the mnemonic BOH at Birth: BCG, OPV-0, and Hepatitis B are administered at birth.

Nutrition & Screening - Neglected High-Yield Areas

Nutrition and Screening in PSM is an easy 3-4 mark topic that many FMGE aspirants fail to prepare for.

Protein Energy Malnutrition (PEM): The WHO categorizes malnutrition based on weight-for-age (underweight), height-for-age (stunting), and weight-for-height (wasting). Kwashiorkor is characterized by edema, flaky-paint dermatosis, and fatty liver - it is caused by protein deficiency and sufficient calories. Marasmus appears with extreme wasting, old man facies, and no edema - it is caused by a complete deficiency of calories. These two are the differences that are posed in almost every FMGE paper.

Vitamin A deficiency is diagnosed using its ocular manifestations: night blindness (the first symptom), conjunctival xerosis, Bitot spots, corneal xerosis, and keratomalacia (irreversible). The most frequently tested sign is the pathognomonic Bitot spots.

Screening criteria - the Wilson and Jungner criteria (WHO, 1968) are used to determine when mass screening is warranted. The condition should be a major health issue, treatment should be accepted, and diagnostic and treatment facilities should be accessible. These ten criteria are a source of direct-recall questions.

FMGE High-Yield Points

NTEP has replaced RNTCP; the target of TB eradication is 2025; the main diagnostic tool is CBNAAT/TrueNat; the treatment is a daily FDC regimen (not intermittent DOTS).

NACP Phase V adheres to the policy of Test and Treat - ART started irrespective of the CD4 count. First-line: TLD (Tenofovir + Lamivudine + Dolutegravir).

Sensitivity is disease catching (high in screening); Specificity is disease exclusion (high in confirmation). Neither is based on prevalence, whereas PPV and NPV are.

Odds Ratio = case-control study. Relative Risk = cohort study. The most prevalent Biostatistics error in FMGE is the confusion between the two.

BCG is the only standard vaccine administered intradermally. The mnemonic "BOH at Birth" - BCG, OPV-0, Hepatitis B.

Kwashiorkor = edema + flaky-paint skin + fatty liver (protein deficiency). 

Marasmus = wasting + no edema (complete deficiency of calories).

The most commonly tested symptom of Vitamin A deficiency is the spots of Bitot - triangular foamy conjunctival spots.

Incidence is a measure of new cases; Prevalence = Incidence x Duration. Chronic diseases always have a higher prevalence.

Secondary Attack Rate does not use the index case as the denominator - a typical exam trap.

The difference between Type I error (false positive, alpha = 0.05) and Type II error (false negative, beta) is often tested by examiners. Power = 1 − beta.

Commonly Asked Questions

Q1: How many questions are in the FMGE of PSM? PSM/Community Medicine is one of the 4 highest-weighted subjects, with approximately 25-30 questions out of 300 in FMGE. Regular scoring in this case can be the sole factor to close the gap to the 150-mark passing point.

Q2: What is the difference between Sensitivity and Specificity? Sensitivity is the ability of a test to correctly identify those with the disease (true positive rate). Specificity is the ability to correctly identify those without the disease (true negative rate). In screening tests, Sensitivity is considered; in confirmatory tests, Specificity is considered.

Q3: Which National Health Program is most frequently tested in FMGE? The most commonly tested is NTEP (National Tuberculosis Elimination Programme), and then NACP (HIV/AIDS) and NVBDCP (vector-borne diseases). The questions are based on the diagnostic algorithm, treatment regimen, and the current elimination targets.

Q4: What is the initial ART regimen in NACP Phase V? The current first-line ART regimen is TLD - Tenofovir + Lamivudine + Dolutegravir. This treatment is started in all newly diagnosed HIV-positive persons under the policy of Test and Treat, irrespective of the CD4 count.

Q5: Which vaccine is given intradermally in India's Immunization Schedule? The only vaccine in the regular Universal Immunization Programme that is administered through the intradermal route is BCG (Bacillus Calmette-Guerin), which is given at birth on the left upper arm. fIPV is intradermal as well, but was introduced later.

Q6: PSM in FMGE - theory-based or clinical? Recent FMGE papers indicate a change to scenario-based PSM questions. Rather than directly asking "What is Sensitivity?", the exam gives you a 2x2 table and asks you to compute it. The questions for the National Health Program are presented as community-based clinical vignettes. Pure recall still accounts for about 60% of PSM questions.

CLINICAL PEARL

In PSM, the student who can name 15 National Health Programs, their targets, and strategies will score higher than the student who has read the entire Epidemiology chapter but has not read the programs.

I have been observing students studying to take licensing tests for over 10 years, and I can tell you this: PSM rewards the organized mind. Construct tables, memorize formulae, and revise thrice - your 25 marks are awaiting.
