Introduction
If you’re preparing for JEE Main, you’ve probably heard the phrase “memory-based questions” thrown around countless times. But here’s the thing—these questions aren’t just random snippets floating on the internet. They’re actual exam questions that thousands of aspirants tackle every year, and analyzing them is like having a blueprint of what NTA (National Test Agency) values most.
JEE Main 2026 Session 1 Day 1 brought a mix of challenging and straightforward questions across Physics, Chemistry, and Mathematics. Understanding the patterns, difficulty levels, and topics emphasized in these memory-based questions can dramatically shift your exam strategy. Whether you’re a first-time taker or retaking the exam, these insights are goldmines for your preparation.
This guide breaks down the real questions from Session 1, analyzes what makes them tick, and shows you how to leverage this information for better scores. Let’s dive in!
Physics Questions from JEE Main 2026 Session 1
What Physics Topics Dominated Session 1?
The Physics section of JEE Main 2026 Session 1 Day 1 leaned heavily toward mechanics and modern physics. Out of 20 questions, mechanics-based problems accounted for roughly 40%, while optics and modern physics shared the remaining weightage.
One standout question involved circular motion and friction—a topic that often trips up students. The question required understanding the relationship between centripetal force and the coefficient of friction on an inclined circular track. Rather than being a straightforward calculation, it demanded conceptual clarity.
Another memorable question tested thermodynamics principles, specifically the first law of thermodynamics applied to cyclic processes. Students had to interpret a P-V diagram and calculate work done and heat absorbed—a classic setup that rewards deep understanding over rote memorization.
Key Physics Insights
The exam pattern revealed that NTA values questions requiring:
- Multi-step problem-solving approaches
- Integration of concepts (combining two or three topics)
- Real-world application scenarios
- Diagram interpretation skills
Questions on electromagnetism also appeared, focusing on electromagnetic induction and Lenz’s law. What surprised many aspirants was the emphasis on physical reasoning rather than plug-and-play formulas.
Pro tip: Don’t just memorize formulas. Understand the “why” behind each concept. This single shift in your approach can boost your JEE Main exam performance significantly.

Chemistry Questions Analysis
Organic, Inorganic, and Physical Chemistry Breakdown
Chemistry in Session 1 was relatively balanced across its three pillars:
Organic Chemistry (~35% of questions) focused on reaction mechanisms and synthesis pathways. One standout question involved predicting products of a multi-step organic reaction, requiring students to understand electron-donating and electron-withdrawing effects. This wasn’t about memorizing reactions; it was about applying fundamental concepts.
Inorganic Chemistry (~30% of questions) emphasized coordination compounds and d-block chemistry. Questions tested concepts like CFSE (Crystal Field Stabilization Energy) and the magnetic properties of complexes. A notable question required calculating the number of unpaired electrons in a transition metal complex—a skill that combines conceptual knowledge with calculation ability.
Physical Chemistry (~35% of questions) covered equilibrium, kinetics, and electrochemistry. One question tested the effect of temperature and pressure on equilibrium constant—a concept that many students overlook despite its importance. Another involved rate laws and order of reactions, where students had to deduce the reaction mechanism from experimental data.
What Made These Chemistry Questions Tricky?
The chemistry questions in JEE Main 2026 Session 1 required:
- Understanding molecular orbital theory
- Applying concepts to unfamiliar scenarios
- Balancing theoretical knowledge with practical problem-solving
- Careful reading to avoid silly mistakes
Mathematics Questions and Patterns
Algebra, Calculus, and Geometry Coverage
Mathematics is often the deciding factor in JEE Main scores, and Session 1 demonstrated this clearly.
Algebra (~30% of questions) included problems on quadratic equations, sequences, and series. One question required finding the sum of an infinite series with a specific pattern—a classic JEE problem that rewards pattern recognition.
Calculus (~40% of questions) dominated the session, with heavy emphasis on differentiation and integration. Questions ranged from finding tangent lines to curves (requiring chain rule and product rule applications) to definite integrals involving trigonometric substitutions. One particularly challenging question combined limits, derivatives, and optimization—a three-in-one problem that tested overall conceptual strength.
Geometry (~30% of questions) covered conic sections, 3D coordinate geometry, and vector algebra. A standout question involved finding the equation of a plane perpendicular to a line and passing through a specific point—a topic that requires spatial visualization skills.
Common Mistakes to Avoid
Students often stumble on:
- Sign errors in calculus—a simple mistake that costs precious marks
- Missing special cases in algebra problems (like when a = 0 or b = 0)
- Coordinate system confusion in 3D geometry
- Calculation oversights rather than conceptual gaps
Interestingly, the mathematics questions in Session 1 weren’t necessarily harder than previous years—they simply required better time management and attention to detail.

Frequently Asked Questions
Q1: How can I use memory-based questions effectively in my preparation?
Memory-based questions serve as study guides showing which topics and question types NTA prioritizes. Don’t just solve them; analyze the solution methodology, identify the core concept being tested, and practice similar variations.
Q2: Are memory-based questions a reliable source for JEE Main preparation?
Absolutely! They represent actual exam patterns, difficulty levels, and topic weightage. However, they should complement, not replace, a comprehensive study plan covering the entire syllabus.
Q3: What’s the best strategy for tackling Physics problems in JEE Main?
Focus on conceptual understanding first, then practice numerical applications. For Physics, building intuition about why things happen (Lenz’s law, Newton’s laws) matters more than memorizing formulas.
Q4: How much time should I dedicate to Chemistry memorization versus problem-solving?
Aim for a 40-60 split—40% memorization (facts, periodic table properties, named reactions) and 60% problem-solving and concept application. This balance ensures both breadth and depth.
Q5: Why do students struggle with Mathematics in JEE Main despite practicing?
Most struggle due to time pressure and calculation errors, not conceptual gaps. Practice solving problems under timed conditions and develop shortcut techniques for recurring problem types.
Q6: When should I start analyzing memory-based questions during my preparation?
Begin reviewing memory-based questions about 2-3 months before your exam. This timing allows you to identify weak areas and address them with targeted revision.
Conclusion
Memory-based questions from JEE Main 2026 Session 1 Day 1 reveal a clear trend: NTA values conceptual understanding, multi-step problem-solving, and the ability to apply knowledge in varied contexts. Whether it’s understanding the physics of circular motion, mastering chemistry synthesis pathways, or solving calculus problems with precision, success requires a balanced approach.
Don’t chase questions—chase concepts. Use memory-based questions as stepping stones to identify gaps, strengthen fundamentals, and build confidence.
