How To Prepare Physical Chemistry For NEET?

Most NEET aspirants often misjudge the challenges that could be encountered in the Chemistry section of NEET. It could either be due to prioritizing the Biology section or devoting more time to solving Physics numericals. Little importance is given to Chemistry, which shows up at the time of exams, which leads to unnecessary fright and hence low scores in the section.

NEET Chemistry section comprises 25% of the question paper. 45 questions out of 180 are asked from Chemistry. Out of these 45 questions, 15 questions are asked from the Physical chemistry section. Unlike other sections of Chemistry, Physical chemistry involves numericals. The pattern of questions appearing in the Chemistry section is difficult to deduce in comparison to Physics and Biology as it keeps varying. Since Physical chemistry shows most variations compared to other sections, it requires all the more attention. Over the years, however, it has been inferred that theory-based questions for numericals have appeared more often. Such questions can be easily cracked by those who have followed NCERT thoroughly.

How To Prepare Physical Chemistry For NEET? – Key Topics In Physical Chemistry Chapters

As it is, the syllabus of NEET is vast. Knowing important topics in a particular chapter becomes all the more necessary to segregate what is important and what is not. While all of us know what the NEET syllabus is for Chemistry and what is to be studied, what sets apart toppers from other candidates is that they know exactly what not to study. A clear distinction between important and not so important topics sets the path right and clear. So, do not waste your precious time, instead, focus on strengthening important concepts.
