The NEET UG 2025 exam is the most important medical entrance exam in India for students who want to get admission into MBBS, BDS, BAMS, BHMS, and other medical courses. This year, the exam was held on May 4, 2025, in a pen-and-paper (offline) mode. Lakhs of students appeared for the exam across thousands of centers in India.

The NEET 2025 question paper had a total of 180 multiple-choice questions (MCQs) from Physics, Chemistry, and Biology (Botany + Zoology). The total duration of the exam was 3 hours, and the maximum marks were 720.

The marking scheme followed the usual pattern:

•  +4 marks for every correct answer
•  -1 mark for every wrong answer
•  No marks for unanswered questions

NEET 2025 Question Paper Pattern – What Changed?

The NEET 2025 paper pattern followed the updated format announced earlier by NTA. As per the latest guidelines, the optional Section B was removed, and students had to attempt all 180 questions. This change was officially notified before the exam, so most students were aware and had adjusted their preparation accordingly.

This year’s pattern was more straightforward, but at the same time, it required full syllabus preparation. Since there were no choices, students had to study every chapter and topic in detail. This increased the pressure to revise thoroughly and practice time management.

Here is the NEET 2025 paper structure:

The NEET UG 2025 exam pattern was uniform for all candidates, making the exam balanced but demanding. Every student had to attempt the same number of questions with no optional skipping, which made accuracy and time management very important.

NEET 2025 Subject-Wise Paper Analysis

The NEET 2025 question paper had a mix of easy, moderate, and difficult questions across all three subjects — Physics, Chemistry, and Biology. However, many students felt this year’s paper was more time-consuming and concept-based than previous years. Let’s look at how each subject was structured and what kind of questions were asked.

Physics—Toughest Section This Year

Physics was widely reported to be the most difficult and lengthy part of the NEET 2025 paper. Most of the questions were numerical and concept-driven, requiring careful calculation and time. Students found it challenging to complete the Physics section within the allotted time.

• Class 11 Questions: 22
• Class 12 Questions: 23
• Major Topics:
  • Moving Charges & Magnetism
  • Current Electricity
  • Ray Optics
  • Laws of Motion
  • Semiconductors

Many students said they had to rush through the rest of the paper after spending too much time on Physics.

Chemistry – Lengthy and Tricky

Chemistry was moderate to tough, with many questions designed to test deep conceptual knowledge. The paper had a mix of Physical, Organic, and Inorganic Chemistry, but questions were more detailed and required careful reading.

• Class 11 Questions: 22
• Class 12 Questions: 23
• Question Type Breakdown:
  • Physical Chemistry: 16 questions
  • Organic Chemistry: 17 questions
  • Inorganic Chemistry: 12 questions
• Popular Topics Covered:
  • Coordination Compounds
  • Organic Chemistry Basics
  • Equilibrium
  • Hydrocarbons
  • Thermodynamics

Many Chemistry questions involved statement-based and match-the-column formats, which increased the difficulty and length of the paper.

Biology – Scoring but Long

Biology was considered the most scoring subject, but many students said it was lengthier than expected. The questions were largely NCERT-based, but some options were confusing, and a few questions were outside the direct lines of NCERT.

• Total Questions: 90
  • Class 11: 40 questions
  • Class 12: 50 questions
• Important Chapters Covered:
  • Molecular Basis of Inheritance
  • Sexual Reproduction in Flowering Plants
  • Plant Kingdom
  • Human Reproduction
  • Biotechnology

Biology tested memory and understanding of NCERT line-by-line. Time management was key to complete all 90 questions on time.

Summary

NEET 2025 Paper Difficulty Level and Question Type Breakdown

The NEET 2025 paper was designed to test both accuracy and application of concepts across all three subjects. While some questions were direct and easy, many required logical thinking, detailed calculations, and in some cases, interpreting multi-statement formats.

According to the complete analysis by NEET Support, this year’s exam had a balanced mix of easy, moderate, and difficult questions, with a noticeable increase in application-based formats. Here’s how the difficulty was distributed:

NEET 2025 Difficulty Level – Subject-Wise Distribution

• 28.3% of the questions were tough
• 38.3% were of moderate difficulty
• 33.3% were relatively easy

NEET 2025 Question Format – Type of Questions Asked

NEET 2025 featured a variety of question types, especially in Chemistry and Biology. These formats required not just knowledge, but also attention to detail and logical reasoning.

Chemistry and Biology had the highest variety of question formats, making these sections longer and requiring more mental focus.

What This Means for Students

• Physics was the least varied in format but had the most calculation-based questions.
• Chemistry tested students through logical pairing, multiple statements, and advanced formats.
• Biology, while largely from NCERT, was designed to check deep reading and included assertion-reasoning and diagram-based questions.

Tip: Students preparing for NEET 2026 should focus not just on theory but also on practicing different question types under timed conditions.

Expert Opinion

According to NEET Support experts, the NEET 2025 exam was designed to assess both conceptual clarity and application of knowledge. While the paper was challenging, it was also a great opportunity for students who thoroughly understood the NCERT syllabus and practiced problem-solving under time pressure.

• Physics was the most difficult subject, with lengthy calculations and complex conceptual questions, particularly in topics like Electrodynamics and Wave Optics.
• Chemistry was a mix of moderate and tough questions, requiring deep understanding of organic reactions and coordination compounds.
• Biology, while largely based on NCERT, required good time management due to the length of the paper and the variety of question types.

For students looking to secure a good rank, we recommend focusing on time management, practice, and understanding key concepts. The NEET counseling process can be tricky, but with proper guidance, students can make informed choices about their college and course preferences.
