NEET UG: Chapter Weightage of Physics, Chemistry and Biology in NEET Paper

NEET is one of the two most difficult medical entrance examinations. Many of you preparing for the same have enquired about the possible chapter-wise weightage in NEET 2017. Here is a result based on analysis of the previous year’s question paper.


Biology for a medical entrance is mainly Zoology & Botany. The following table shows topic wise weightage of the Question paper of NEET 2016. It can be observed that Biological classification, enjoying a vast portion of the syllabus occupied 9 of the total 90 questions asked. There are topics which were having just one question such as digestion & absorption, Transportation in plants etc. But, these were all scoring questions which can’t be ignored based on just their weightage in NEET. Everything said & done biology of NEET will throw questions from the following topics with a slight change in their weightage.

Honestly, nothing much can be drawn about weightage of chemistry in NEET based on NEET Chemistry question paper, but s-block,p-block,d-block & f-block are the favourite chapters of question paper designers. Special reactions in organic chemistry should also be thoroughly prepared. You can take a look into chemistry topic wise weightage to judge your preparations in chemistry for NEET & how should you go about it in the remaining time.
