Was JEE Main 2026 Shift 1 Physics easy or tough as per student feedback?

Student feedback indicates Physics was Easy to Moderate. The paper was largely formula-based, with many direct questions from NCERT. Aspirants with clear basic concepts found it scoring.

What did students say about the difficulty of Mathematics in JEE Main Shift 1?

Mathematics was widely reported as the toughest and most time-consuming section. While the concepts were standard, the calculations were lengthy, particularly in Calculus and Algebra.

Was Chemistry NCERT-based in JEE Main 2026 Shift 1?

Yes, Chemistry was heavily NCERT-centric. Students noted that Inorganic and Organic Chemistry questions were picked almost directly from NCERT textbooks, making it the fastest section to complete.

Which subject was most time-consuming in Shift 1 JEE Main 2026?

Mathematics was the most time-consuming. Students reported spending 70–90 minutes on this section due to complex multi-step problems in Vectors, 3D Geometry, and Calculus.

How many questions were numerical-based vs theory-based in Shift 1?

The paper followed the standard NTA pattern: 20 Multiple Choice Questions (MCQs) and 10 Numerical Value Questions (of which 5 were to be attempted). Physics and Chemistry had a healthy mix of theory, while Maths was entirely numerical/calculation-based.

Were there surprise or unexpected questions in JEE Main 2026 Shift 1?

Some students noted a slight increase in statement-based questions in Chemistry. In Physics, some questions on Modern Physics and Semiconducting devices required deeper conceptual clarity than usual.

Were questions repeated from previous year JEE Main papers in Shift 1?

Yes, several students mentioned that the pattern and logic of questions in Physics and Mathematics were very similar to the 2024 and 2025 January session papers, particularly for topics like Vectors and Current Electricity.

Which topics carried maximum weightage in Physics (Shift 1)?

Experts identified Modern Physics, Mechanics, and Electromagnetism as high-weightage areas. Specifically, questions on De Broglie wavelength, Current Electricity, and Electrostatics were prominent.

Why was Mathematics considered lengthy or tough in Shift 1?

According to experts, the difficulty stemmed from calculation-intensive problems. Questions in Vectors & 3D Geometry and Integration required significant algebraic manipulation, which exhausted students' time.
