How to approach SBA and True/False MCQs in Final MBBS & ERPM

Knowing your medicine is necessary but not sufficient — good MCQ technique can lift your score meaningfully on the same knowledge. Here's how to approach the two formats you'll face in Final MBBS and ERPM.

Read the stem properly — twice

Most avoidable errors come from misreading the question, not from not knowing the answer. Read the stem carefully and notice the small words that change everything: most likely, initial, definitive, except, not. "What is the most appropriate initial investigation?" is a different question from "the definitive investigation." Underline these in your mind before you look at the options.

Single Best Answer (SBA) technique

Form your answer before reading the options

Where you can, decide what you expect the answer to be before looking at the choices. This stops the distractors from leading you astray.

Eliminate, then choose the best — not just a correct one

SBA options are often several "correct" statements where only one is the best answer for that specific stem. Eliminate the clearly wrong ones, then ask which remaining option best fits what the question actually asked.

There's no negative marking on SBA — never leave it blank

In MCQMED, SBA scores +5 for correct and 0 otherwise. If you're down to two options, make your best guess — a blank scores the same as a wrong answer, so always commit.

True/False technique

Treat each statement independently

Don't let one statement colour your judgement of the next. Each is a separate true-or-false decision about a single fact.

Respect negative marking — guessing has a cost

True/False rewards accuracy and penalises wrong answers: +1 right, −1 wrong, with a floor of zero per question. The maths matters. If you genuinely know a statement, answer it. If you can confidently narrow it but aren't sure, a calculated answer is reasonable. If you have no idea at all, leaving it blank (0) is often better than a coin-flip that risks −1.

Watch the absolutes

Words like always, never, and only make a statement easier to falsify — biology has exceptions. Conversely, hedged words like may, can, and is associated with are easier to satisfy. These aren't rules, but they're useful prompts when you're genuinely on the fence.

Manage your time

Work out roughly how long you have per question and keep moving. Don't sink five minutes into one stem — flag it, answer your best guess, and return if time allows. A question you leave blank because you ran out of time scores nothing; a reasoned guess at least has a chance.

Common traps to avoid

• Changing answers without reason. Your first instinct, when you know the topic, is often right. Only change an answer if you have a concrete reason.
• Over-reading the stem. Don't invent complications the question didn't mention. Answer what's asked.
• Pattern-matching a single keyword. A buzzword might point to the classic diagnosis — but check the whole stem fits before committing.
• Ignoring the explanation when you practise. The point of practice questions is to learn the reasoning, not to score points. Read every explanation.

Practise the format, not just the facts

Exam technique is a skill, and like any skill it improves with reps. The more SBA and True/False questions you do under realistic conditions, the more automatic this all becomes. That's what MCQMED is for — thousands of questions in both formats, each with an explanation so every attempt teaches you something.
