About JEE Main

JEE Main is the first stage of the JEE (Joint Entrance Examination) pathway and the most widely accepted engineering entrance exam in India. Conducted by NTA (National Testing Agency) multiple times a year, JEE Main scores are used for admission to NITs (National Institutes of Technology), IIITs (Indian Institutes of Information Technology), and other centrally funded technical institutions. JEE Main rank is also mandatory for eligibility to appear in JEE Advanced for IIT admissions.

Exam Pattern (JEE Main 2026):
- Total Questions: 90 (30 per subject — Physics, Chemistry, Mathematics)
- Total Marks: 300 (4 marks per correct, -1 per wrong)
- Duration: 3 hours (180 minutes)
- Mode: Computer-Based Test (CBT) / Pen-and-Paper (BTA)

Question Types:
- MCQ (Multiple Choice Questions): 75 questions (choose from 4 options)
- Numerical Value Questions: 15 questions (enter numerical answer)
- Typically 5 from each subject; only 5 attempted per subject in numerical section

Physics Topics:
- Mechanics (Kinematics, Laws of Motion, Work-Energy-Power, Rotational Motion, Gravitation)
- Thermodynamics & Thermodynamic Processes
- Electrostatics & Current Electricity
- Magnetism & Electromagnetic Induction
- Optics (Ray & Wave)
- Modern Physics (Dual Nature, Atoms, Nuclei, Semiconductors)
- Waves & Oscillations, Electromagnetic Waves

Chemistry Topics:
- Physical Chemistry (Chemical Bonding, Thermodynamics, Equilibrium, Electrochemistry, Chemical Kinetics, Solutions)
- Organic Chemistry (Basic Principles, Hydrocarbons, Alcohols, Aldehydes, Amines)
- Inorganic Chemistry (Periodic Table, p-Block, d & f Block, Coordination Compounds)

Mathematics Topics:
- Algebra (Matrices, Determinants, Complex Numbers, Probability, Vector Algebra)
- Calculus (Limits, Continuity, Differentiation, Integration, Differential Equations)
- Coordinate Geometry (Straight Lines, Circles, Parabola, Ellipse, Hyperbola)
- Trigonometry, Mathematical Reasoning, Statistics

Eligibility: Passed 10+2 or equivalent with Physics, Chemistry, and Mathematics. Minimum aggregate: 75% (relaxed to 65% for reserved categories).

Career Opportunities: NIT graduates command ₹6-20 LPA starting salaries. IIIT graduates in CS/IT often receive ₹10-40 LPA. JEE Main qualifiers also have the option to attempt JEE Advanced for IIT admission.

Why Practice JEE Main Mock Tests: JEE Main tests speed, accuracy, and NCERT-level depth. Our practice tests replicate the actual NTA pattern with both MCQ and numerical questions, helping you achieve a top rank for NIT/IIIT admission.
