It is essential to develop an effective preparation strategy to achieve decent marks, succeed in the examination and gain admission to the prestigious IITs. Thus, it is necessary to have a strong understanding of the syllabus.
The Chemistry syllabus of IIT JEE Advanced is considered to be the lengthiest. However, owing to several fact-based questions in the form of reactions, etc it also becomes the easiest. You should have a thorough understanding of the Chemistry syllabus to optimise your preparation strategy.
