“Verified” is a claim, so this page says exactly what it means on NEET720. Every one of the 80,724 active questions in the bank has passed the checklist below, and every question can be challenged from inside the app. The process is run by the NEET720 content team at Digital Sea India Pvt. Ltd..
The checklist
- Solution verified independently. The marked answer is checked against a solution worked without reference to the source key. A question whose worked answer disagrees with its key is not published until the disagreement is resolved.
- Syllabus mapped. Each question is assigned a chapter, topic and concept in the current NTA NEET (UG) syllabus. Questions that cannot be mapped are excluded rather than filed under a loose heading.
- Distractors justified. Every wrong option must correspond to a plausible mistake, so that the question tests understanding rather than the ability to spot the odd one out. Where possible, the specific misconception behind an option is recorded and surfaced in the explanation.
- Answer positions balanced. Correct answers are distributed across options A to D by a deterministic shuffle, so a student cannot gain by always picking the same letter. Assertion-Reason items keep their conventional fixed option order.
- Diagrams drawn, not described. Diagram and graph questions carry the actual figure, reviewed for accuracy; a question that needs a figure it does not have is not published.
- Duplicates removed. New batches are compared against the whole existing bank, and near-duplicate stems are dropped before import.
- Error reports acted on. Every question has a flag button in the app. Reports enter a review queue; a confirmed error is corrected or the question is withdrawn. See the editorial and correction policy.
Two kinds of questions, two rules
- Previous-year questions reproduce the official paper's question and options; every explanation is written by NEET720. Where a year's paper contained a question later declared bonus or withdrawn by NTA, it is not shown as a practice item.
- Original and predicted-pattern questions are NEET720's own compositions written in the style of past papers. They are never leaked or official questions, and the app labels them accordingly.
A real example, annotated
Question CHE-INORG-ANOM-0001 from Classification of Elements and Periodicity (Chemistry), exactly as it appears in the bank.
The first element of a group in the p-block or s-block often shows anomalous behaviour compared to other members of its group mainly because it has
- A.a fully filled f-subshell that shields the nucleus poorlyWhy a student might pick this: Confuses first-row anomaly (no d-orbitals, small size) with lanthanoid contraction reasoning, which is irrelevant to period 2.
- B.the lowest ionization enthalpy in its groupWhy a student might pick this: Mistakes a consequence-like trend statement (not even generally true, since first members usually have the HIGHEST IE in the group) for the underlying cause.
- C.the highest atomic mass among group membersWhy a student might pick this: Confuses atomic mass trend (which increases down a group, so first member has the lowest, not highest) with the actual structural cause.
- D.no d-orbitals available in the valence shell and a comparatively small size with high charge densitycorrect
- Quick explanation (what the student sees first)
- The first element of a group (period 2 mainly) lacks d-orbitals in its valence shell, has an unusually small size and high nuclear charge density, giving it different bonding capability, maximum covalency, and diagonal similarity to a period-3 element one group to the right.
- Detailed explanation
- Period 2 elements (Li to F) show anomalous behaviour relative to their own group because: (i) they have only 2s and 2p orbitals available (no 2d), restricting their maximum covalency to 4 (e.g., cannot form NF5 or BF6^3- easily as heavier congeners can with d-orbitals); (ii) their atomic/ionic size is exceptionally small with high charge/radius ratio, giving unusually high electronegativity, ionization enthalpy and polarizing power compared to the rest of the group; (iii) absence of d-orbitals also affects pπ-pπ multiple bonding ability (e.g., N2 has a strong pπ-pπ triple bond, unlike P which prefers single bonds). This combination — small size, no valence d-orbitals, high charge density — is the root cause of the first-member anomaly, and it is this same high charge density that drives diagonal relationships (Li-Mg, Be-Al, B-Si).
- Common mistake recorded during review
- Attributing the anomaly to f-orbital shielding or misremembering the IE/mass trend direction
- Concept tested (used for mastery tracking)
- Cause of anomalous behaviour of the first member of a group
The “concept tested” field is what makes the product work: mastery is tracked per concept, so a wrong answer here lowers the student's mastery of that concept specifically, and Fix My Weakness can pick sibling questions on the same concept.
What this does not claim
- It does not claim that any question will appear in NEET. Predicted-pattern questions are practice material.
- It does not claim zero errors. Errors are found and fixed through the report loop; the policy page explains how.
- Readiness scores are internal practice metrics computed from a student's own attempts, not predictions of a NEET result.
