How to review a wrong answer: a five-step routine for NEET PG practice

Study methodPublished 28 September 2026 · Recallab

A wrong answer is the most useful thing a practice session gives you. Most candidates spend ten seconds on it: read the right option, nod, move on.

The explanation tells you what the answer is. It rarely tells you why you went the other way, and that is what decides whether you make the same mistake next week. The routine below takes about two minutes a question. It is shown on three real Recallab MentorQs, each one easy to miss for a different reason. Try each question first, then read the review under it.

The five-step review

Before you read anything, say why you chose your option. One sentence: "I picked D because…". This is the step most people skip, and it is the only one that shows your actual error.
Read why your option is wrong before why the key is right. A good explanation refutes every wrong option; start with the one you chose.
Name the kind of error. A misread question, a fact the wrong way round, two similar facts confused, or a fact you did not have. The table below says what each one needs.
Write the fix in one line, in your own words. Not the key fact copied out, but the correction to your sentence from step 1.
Answer it again later, not now. Straight after the explanation you will get it right from memory of the answer. A few days later, that attempt is the real test.

Kind of error	What it sounds like	What fixes it
A misread question	"I knew it; I answered something else"	A reading habit: say the last line of the stem back before the options
A fact the wrong way round	"I knew they were linked, not which way"	Learn the link with its direction
Two similar facts confused	"I mixed it up with the other one"	Learn the two side by side, with the feature that separates them
A fact you did not have	"I had never seen this"	Learn it, then test it again in a few days

Example 1: answering a different question

Recallab example 1 · a misread question

Four views at laryngoscopy are drawn in the figure. Which view is the first at which a tracheal tube cannot ordinarily be passed under direct vision?

Four views down a laryngoscope, numbered 1 to 4: the whole glottis with both cords; only the back of the cords and the arytenoids; the epiglottis alone; and no epiglottis at all. Below them, unlabelled, a bougie, a laryngeal mask, a videolaryngoscope, and a scalpel with a tracheal tube. — Recallab question 55080. Four views at laryngoscopy, as the anaesthetist sees them.

AView 3
BView 2
CView 1
DView 4

Show the answer and explanation

Answer: A. View 3

View 3, where the epiglottis is seen and nothing beneath it. The tube cannot be watched into the cords, so a bougie or a videolaryngoscope is reached for. In view 2 the arytenoids are still visible, so a tube can usually be steered between them.

Why view 4 (D) is wrong: it is worse still, but it is not the first view at which direct intubation fails. View 1 (C) is a full view, the easiest of the four.

The review. Suppose you chose view 4. Step 1: "I picked view 4 because nothing at all can be seen." That is true, and it is the trouble: the question asked for the first view at which a tube cannot be passed, not the worst. Step 3 names it a misread question, and no fact needs learning. The one-line fix is: "I answered worst when it asked first." The habit that prevents it is to say the last line of the stem back to yourself before looking at the options. For management questions, where one word in the last line decides the answer, see next best step.

Example 2: a fact the wrong way round

Recallab example 2 · a fact the wrong way round

Three scans at thirty four weeks are drawn in the figure with the uterus divided into four quadrants and the deepest pocket measured in each. Scan 2 shows oligohydramnios. Which cause should be looked for first?

Three uteri at thirty four weeks, each divided into four quadrants with the deepest pocket of fluid measured in each. Scan 1 totals 18 centimetres, scan 2 totals 4 with the fetus crowded and the uterus moulded round it, and scan 3 totals 30. — Recallab question 55091. Three scans with the deepest pocket measured in each quadrant.

AMaternal hyperglycaemia
BImpaired fetal swallowing
CRupture of the membranes
DFetal anaemia

Show the answer and explanation

Answer: C. Rupture of the membranes

Rupture of the membranes. After the first half of pregnancy, amniotic fluid is fetal urine, so too little means it is either leaking out or not being made. Ruptured membranes are the commonest cause and are sought first; if the membranes are intact, the fetal kidneys and bladder are checked next.

Why impaired swallowing (B) is wrong: a fetus that cannot swallow cannot clear the fluid, so it builds up: polyhydramnios, the opposite problem. Maternal hyperglycaemia (A) also causes too much fluid, and fetal anaemia (D) leads to hydrops, often with polyhydramnios.

The review. Suppose you chose impaired swallowing. Step 1: "Swallowing changes the amount of fluid, so I picked it." The link is real; the direction is wrong. Step 3 names it a fact the wrong way round, which is the easiest kind to fix, because you already hold the fact. The one-line fix keeps the direction: "Too little fluid: leaking or not made. A fetus that cannot swallow gives too much."

Example 3: two similar facts confused

Recallab example 3 · two similar facts confused

Which condition's marker surges in every healthy baby in response to the cold after birth, so that a sample in the first twenty four hours gives a false positive?

AThe thyroid condition
BThe amino acid condition
CThe adrenal condition
DThe red cell condition

Show the answer and explanation

Answer: A. The thyroid condition

A newborn screening card with four blood spots, one of them rejected, and four panels for the conditions screened: the thyroid with an early peak on a curve, an amino acid disorder, the adrenal gland and a red cell. Beside it a baby's heel with the side of the heel marked for the prick. Below, a timeline from birth to seven days with the first 24 hours crossed out and a sampling window from 48 to 72 hours. — Recallab question 55148. The screening card and the sampling window, from the question's explanation.

The thyroid condition. Thyroid stimulating hormone surges in every newborn in the hours after birth, a normal response to the cold. A sample taken too early flags a healthy baby, so the window opens at 48 hours, once the surge has passed.

Why the adrenal condition (C) is wrong: its marker, 17-hydroxyprogesterone, is also high in the first days, but from the stress of birth, not the cold surge. The amino acid condition (B) is the reason to wait until feeding is established, which does not create a false positive; the red cell condition (D) has nothing to do with the timing.

The review. Suppose you chose the adrenal condition. Step 1: "Its marker is high in the first days, so an early sample would flag it." That is true, and it is exactly why the option is tempting. But the stem asks for the marker that surges in response to the cold. Step 3 names it two similar facts confused, and the fix is to learn them as a pair: "Early sample: TSH rises with the cold, 17-OHP with the stress of birth."

Right answers need reviewing too

A correct answer you guessed is a wrong answer that has not cost you anything yet. Rate your confidence as you answer (sure, think so or guess) and put every guess through the same review. The costliest error is the other way round: a wrong answer you were sure of. See lucky guesses and false certainty.

When to answer it again

Answer a missed question again after a few days, not the same evening. If you get it right, leave a longer gap before the next try; if you miss it again, bring it back sooner. Recallab's Due Today brings missed questions back on this kind of schedule, graded by whether you were right and how sure you were.
