MATHEMATICS – Important Chapters for JEE Mains

There is a fair distribution of topics in Mathematics section in JEE Mains. There is almost one question on each chapter. So it is a wise thing to do to study all chapters with equal diligence.

Mathematics can be easily mastered by putting in practice. To make your last lap preparation easier, here is a distribution into basic topics, scoring topics, and essential topics.

CHEMISTRY – Important Chapters for JEE Mains

Chemistry is divided into organic, physical, inorganic chemistry. Some questions in chemistry involve calculations, others are analysis and inference based. it is evermost important to have a rock solid foundation in chemistry to tackle both sorts of problems. To have that, these are the 6 topics you should be confident with.

1. Chemical Bonding
2. Periodic table
3. Carbonyl Compounds and their derivatives
4. Redox reactions, Mole Concept and the concept of equivalents
5. Solid state, solutions and gases theory
6. Thermochemistry and the Second Law of Thermodynamics
