NEET UG 2026 Physics Answer Key Controversy: Experts Demand Revision

The National Testing Agency released the provisional answer key for NEET UG on May 6, 2026. Almost immediately, a particular Physics question concerning the calculation of density using significant figures stirred confusion among candidates, educators, and coaching institutes. Many students have expressed concerns that the answer provided in the provisional NEET 2026 answer key is inaccurately rounded.

Understanding the NEET UG 2026 Physics Question

The contentious NEET UG Physics question required candidates to determine the density of a metallic cube while adhering to significant figure rules. According to the provisional answer key, the correct answer was stated as option 4, which is 7.6. However, numerous reports suggest that the correct answer should actually be 7.7. This discrepancy hinges on the application of rounding rules and significant figures in Physics calculations.

Experts have pointed out that the calculated value derived from solving the question is approximately 7.654. They argue that, based on standard scientific rounding protocols and methodologies aligned with NCERT guidelines, this value should be rounded to 7.7 instead of 7.6. This seemingly minor difference of 0.1 has escalated into a significant issue, as even a single mark can dramatically influence a candidate's All India Rank and their prospects for MBBS admissions.

Implications for NEET UG 2026 Candidates

Under the NEET marking scheme, each correct answer is awarded 4 marks, while 1 mark is deducted for incorrect responses. Consequently, candidates who answered this question expecting full marks are now anxious about potentially losing five marks—four for the unanswered question and one for the negative marking. This concern is particularly acute for those aiming for a perfect score of 720 out of 720, as the acceptance of 7.6 as the correct answer could jeopardize their chances.

Many students who selected 7.7 in the examination are worried about the implications if the NTA does not amend the answer in the final NEET 2026 answer key.

Calls for Revision or Dual Answers in NEET UG 2026

In light of the ongoing debate, students and experts are advocating for the NTA to either revise the NEET UG answer key, changing the correct option to 7.7, or to acknowledge both 7.6 and 7.7 as valid answers. They contend that since the confusion stems from the interpretation of significant figures and rounding methods, students should not be penalized for adhering to the scientific principles taught in schools and coaching institutes.

NEET UG 2026 Objection Window and Result Timeline

Students can raise objections regarding the provisional answer key through the NEET UG 2026 objection window, which will be available soon on the official NTA website at neet.nta.nic.in. Candidates should stay updated on the steps to raise objections and any associated fees.

As for the NEET UG 2026 results, they are expected to be announced approximately one month after the examination. The results will be released in a PDF format, which will include cutoff marks and a merit list for the candidates.
