The paper
What the BCBR exam actually looks like
Confirmed by sitting it. Most of what makes people anxious about this exam turns out not to be true.

This is not a speed test. It is a recognition test. Three hours for a hundred questions is 1.8 minutes each — nobody runs out of time. What separates a pass from a fail is walking in having already seen the question.
Which is why re-reading the course slides is such a poor use of the last two weeks, and why answering questions until they stop surprising you is such a good one.

Three real questions from the free lectures
Nothing to install and no sign-up. These are the actual explanations you get — judge the product on them.
Formulating a research question
Which of the following verbs is preferably used in the statement of objectives of an analytical research study?
Answer: B.
Verb tells you the type of study. ANALYTICAL objectives use comparison verbs: determine, compare, evaluate, examine, assess the association.
DESCRIPTIVE objectives use estimate, describe, measure, document.
'Study' is vague and never acceptable in an objective because it is not measurable.

Literature review
The ability to apply the principles of analysis to identify those studies which are unbiased and valid is called as
Answer: A.
CRITICAL APPRAISAL is the systematic application of principles of analysis to judge whether a study is valid, unbiased and relevant before you use its findings.
Information seeking = finding potentially useful articles; information retrieval = pulling out the relevant subset from a database; systematic review = a full research method with a protocol.
Learn these four terms as a set — this lecture recycles them in at least six different questions.

Introduction to health research
What is appropriate for sample and sample size?
Answer: C.
A sample must satisfy TWO separate requirements, and they are not interchangeable.
Representativeness → the sample mirrors the target population, which gives EXTERNAL validity (generalisability).
Adequacy → enough participants to give the study POWER to detect a true difference, i.e. precision and meaningful inference.
A large but unrepresentative sample and a representative but tiny sample are both useless, so both 'a' and 'b' are needed.

One job: get you past 50
No streaks, no badges, no mastery rings. Competitors have those. We would rather spend the effort on the explanations.

Explanations that teach the distinction
Written for people who are not from a public health background — where the answer turns on two confusable terms, the explanation separates them.

Questions
Before you spend anything
What is the BCBR exam?
BCBR is the Basic Course in Biomedical Research, run by ICMR through the National Institute of Epidemiology. It is a compulsory course for a great many Indian medical professionals, and it ends in an online proctored examination taken at an exam centre.
How many questions are in the exam and what is the pass mark?
100 questions in 180 minutes, and you pass at 50. There is no negative marking, so a guess can only ever help you — never leave a question blank.
Are these the actual exam questions?
No, and anyone telling you otherwise is not being straight with you. These are 690 practice questions covering the pool that students consistently report seeing, written up with worked answers and explanations. We make no claim about what will appear on any particular paper.
How much of it is free?
Five lectures — 150 questions with full explanations — are free forever, with no card and no trial countdown. You only pay if you want the remaining 18 lectures.
Is this a subscription?
No. Every plan is a single payment that unlocks access for a fixed period, and nothing renews automatically. We do not store your card. Most people sit BCBR once, so an auto-renewing subscription would be the wrong shape entirely.
Does it work offline?
Yes. Once a lecture has loaded, it is cached on your device, so you can keep studying on a train or on a hospital floor with no signal. Your answers sync when you reconnect.
Is BCBR Buddy affiliated with ICMR or NIE?
No. It is an independent study aid built by a doctor who sat the exam. It is not affiliated with, endorsed by or connected to ICMR, NIE or any government body.
