IIT JEE Chemistry Preparation Plan

When you hear the word ‘Chemistry’, what images come to mind? Test tubes, atomic structures, periodic tables, laboratory coats, journals or some crazy laboratory explosion? Well, Chemistry is the science of molecules and their transformations; it deals with the composition, structure, and properties of matter. Modern Chemistry dates back to the 17th century, but it is believed that the true origin of Chemistry goes far beyond. It is the branch of Science that is derived from alchemy and is just as fascinating to learn. Also, Chemistry is one of the three core subjects in IIT JEE.

To boost your IIT JEE Chemistry preparation, you must strengthen your conceptual understanding. The plethora of books available in the market is the usual place to start. But these books are commonly available to all. By merely referring to them, what are you doing differently? For an added advantage, refer to the study material which comes along with our online preparation plan for IIT JEE Chemistry. The plan also includes videos which discuss the most relevant questions for IIT JEE Chemistry and their solutions.
What’s more? The online IIT JEE Chemistry preparation plan by TopperLearning and Motion Education has other features like Test Series, Ask the Expert and Mentorship Support. Keep scrolling to know more!
