Frequently Asked Questions: NEET UG Physics

Proven strategies, syllabus guidance, and high-frequency topics for NEET UG Physics.

What is the structure of the Physics section in NEET UG?

The NEET UG Physics paper comprises 50 Multiple Choice Questions worth 180 marks out of 720 total. It is partitioned into Section A (35 mandatory questions) and Section B (15 questions, from which candidates attempt any 10). Each question carries +4 marks for a correct response and -1 mark for an incorrect response. Unattempted questions carry zero penalty.

Are calculators permitted in the NEET UG examination?

No. Calculators, smartwatches, logarithmic tables, and all electronic devices are strictly prohibited in NEET UG. Consequently, NTA calibrates numerical problems so that values simplify with standard approximations (e.g., \(g \approx 10 \text{ m/s}^2\), \(\frac{1}{4\pi\varepsilon_0} = 9 \times 10^9 \text{ N}\cdot\text{m}^2/\text{C}^2\)). Practicing mental arithmetic and dimensional estimation is critical.

Which Physics units are easiest to score in NEET?

Modern Physics (Dual Nature, Atoms, Nuclei), Semiconductor Electronics, Current Electricity, and Thermal Physics offer the highest marks-to-time ratio in NEET. These units typically contribute 14–16 direct, formula-based questions (56–64 marks) that require straightforward calculations compared to rotational mechanics.

How many questions come from Class 11 vs Class 12 Physics?

Typically, the distribution is closely balanced: approximately 45–48% of questions originate from Class 11 (Mechanics, Thermal Properties, Waves) and 52–55% from Class 12 (Electrodynamics, Optics, Modern Physics, Semiconductors). Class 12 concepts carry slightly higher direct weightage in Prelims.

How should medical aspirants approach numerical problem solving?

Follow a three-step method: (1) Identify given variables and required quantity with correct SI units, (2) Check dimensions and eliminate obviously incorrect options before calculating, and (3) Apply standard formulas and verify physical plausibility. Taking timed chapter-wise mock tests trains students to complete each question within 60 seconds.
