NEET 2020 Chemistry Syllabus- Check Detailed Syllabus and Important Topics

NEET Chemistry Syllabus is very vast and can be classified into three parts, namely- physical, organic and inorganic chemistry. However, this classification can be used for general communication purpose only, NEET 2020 covers syllabus for chemistry as prescribed in CBSE class XI and class XII NCERT books.

Students must prepare each unit well in order to perform well in the NEET chemistry exam. The best preparation tip is to prepare the top 10 important topics of chemistry before you start devising any self-study plan. The more time you allot to these chapters higher will be your score in NEET 2020 chemistry section. Not to forget, more the revision, the better is the performance.

Preparation tips to crack NEET chemistry

NEET questions are generally simple, although the syllabus is wide, the questions are repetitive in nature and with a simple twist. Practicing regularly with previous year papers helps a lot.

  • Practice! Practice! Practice: The key to success in chemistry section of NEET is practice.
  • Time management: Candidate need to be quick and wise in the selection of questions to clear the exam with a good score. 
  • Inorganic chemistry must be learned throughout the year: As inorganic chemistry has a vast syllabus and difficult structural diagrams, best to practice them regularly. You must learn the logic behind each statement as it is mostly theory. 
  • NCERT is your X-Factor: NEET questions are mostly asked directly from specific lines of a specific chapter, so try to by heart the concepts with line and a photograph of the page number and corresponding para. This way you can easily mark the answers, as soon as you see the questions.
  • Reference books: Along with NCERT books candidate must refer some other books that give you space for practice.
  • Last day preparation: Make a small pocket manual for yourself where you can keep all the important concepts handy, or a collection of information that can be used for studying the important topics at the last minute. 
  • Never try new things in the last few days: As the chemistry syllabus is quite vast. This requires you, to follow a timetable and study things with some gaps and space, but do not learn anything new in the last few days, if you have not worked with it previously.
  • Last minute revision: Revision is an important part of the syllabus, so just revise everything you have learned in the last few days, so that you are through with all the concepts.
  • Take care of your health: If you are healthy whole year, then only can you work on the plan devised by you for self-study. Best to eat small meals at regular intervals to keep your mind fresh.
