Organic Chemistry: Pay special attention to topics like Stereochemistry, General Organic Chemistry (GOC), and Functional Group Analysis.

Inorganic Chemistry: Chemical Bonding and Coordination Chemistry requires conceptual understanding and should be given adequate attention.

Physical Chemistry: Focus on Thermodynamics and Chemical Equilibrium, as conceptual questions from these chapters are commonly asked.

NCERT Emphasis: JEE Main Chemistry is entirely based on the NCERT syllabus, so thoroughly preparing NCERT textbooks is essential.

Attempt Order: Start with theoretical questions, followed by calculations. Avoid numerical questions in the first 10-15 minutes.


Vectors and 3-D Geometry: These topics offer limited scope for question variation, so mastering them is crucial.

Complex Numbers: Expect 2-3 problems from this topic every year.

Calculus: Focus on Functions and Applications of Derivatives, as graphical approaches can yield easy marks.

Coordinate Geometry: Understand the algebraic calculations and properties of conics thoroughly.

Trigonometry: Although it carries less weight, important formulae in trigonometry should be well-grasped for scoring marks.

Other Topics: Mathematical Reasoning, Determinants, Statistics, and Mathematical Induction should also be covered for quick marks.

Practice: Refer to past JEE Main and sample test papers to understand the exam pattern and question types.
