 🔍 What Students and Experts Said: Exam Overview 

Initial feedback from students and top coaching institutes suggests that Mathematics was the most challenging section, while Physics and Chemistry were comparatively balanced, though conceptually demanding.

• Ramesh Batlish, Senior Faculty at Aakash BYJU’S, rated Paper 1 as moderately to highly difficult, especially due to the lengthy and tricky math problems.
• Ujjwal Singh, CEO of Infinity Learn (Sri Chaitanya), remarked that the overall difficulty level in 2025 was slightly higher than in 2024. Paper 2, in particular, stood out for its complex Physics questions and computational-heavy Math section. Chemistry leaned more toward organic chemistry.

 📘 Subject-Wise Analysis 

🧪 Chemistry: Easy to Moderate

• Most students found Chemistry the most manageable section.
• Heavy focus on organic chemistry, especially amines, oxygen-based compounds, polymers, and named reactions.
• Inorganic chemistry was less prominent but included coordination compounds, mostly straight from NCERT.
• Physical chemistry topics included electrochemistry, thermodynamics, and atomic structure, with some mixed-concept questions.

⚙️ Physics: Balanced and Conceptual

• Physics had a fair distribution of topics, including kinematics, modern physics, rotational motion, capacitors, and optics.
• Questions required deep conceptual understanding, though they weren’t overly lengthy.
• Experts noted that while the questions were manageable, they demanded clarity over memorization.

📐 Mathematics: Time-Intensive and Difficult

• Students widely reported that Math was the hardest section, with lengthy calculations and tricky conceptual applications.
• Topics included integration, matrices, limits, probability, complex numbers, conic sections, permutations & combinations, and 3D geometry.
• Many struggled with time management, as questions were both complex and time-consuming.

 🔄 What Was New in JEE Advanced 2025? 

According to Dr. Brajesh Maheshwari of ALLEN Career Institute, there were several key changes:

• Each paper had 48 questions, with 16 per subject, compared to 17 per subject last year.
• Total marks remained 180 per paper, for a combined 360 marks.
• A major shift was the increase in numerical-answer-type (integer) questions, particularly in Paper 2. These questions did not carry negative marking.

✅ Paper 1 Format

• Section I: 4 single-correct MCQs (+3 for correct, -1 for wrong)
• Section II: 3 multiple-correct MCQs (+4 full correct, partial marking allowed, -2 for incorrect)
• Section III: 6 numerical answer-type questions (+4, no negative)
• Section IV: 3 match-the-following questions (+4 for all correct, -1 for incorrect)

✅ Paper 2 Format

• Section I: 4 single-correct MCQs (+3/-1)
• Section II: 4 multiple-correct MCQs (+4/-2)
• Section III: 8 numerical questions requiring non-negative integers (+4, no negative marking)

 ⏱️ Which Shift Was More Difficult? 

As per Nitin Vijay, Founder of Motion Education, Paper 2 was more challenging than Paper 1.

The increased number of full-value numerical questions without options added complexity. Unlike previous years, there were no paragraph-based questions. The Math and Physics sections in the afternoon shift were particularly time-consuming and concept-driven, while Chemistry remained relatively easier.
