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.

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, as the questions from inorganic chemistry are generally theory-based, so questions are directly asked on the fundamental concepts, sometimes basic configurations are asked, making it easy to answer.
- Time management: As you need to attempt 180 questions in 180 minutes, so 45 minutes time is allotted to every section. You need to be quick and wise in the selection of questions to clear the exam with a good score. This can only be done if the practice is done in accordance with the important topics list given above. The higher the difficulty level of the chapter, lower is the difficulty level of the question asked.
- 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. So you cannot mug up the concepts as it creates confusion. It should be learned in the form of small modules, which can be revised daily at regular intervals, best to click photos of the formulae and diagrams in your mobile and keep checking them regularly like facebook updates, so the impression is registered in your memory.
- NCERT is your X-Factor: NEET exam can be cracked easily if you are thorough with every line of a chemistry book. 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: As NEET questions are mostly based on simple concepts or theoretical, so, it is advised that you work with some good books that give you space for practice. MCQs from Arihant, Objective Biology by Dinesh. O.P Tandon can be useful for practice for physical chemistry.
- 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. Physical chemistry formulae can be learned easily with the help of this manual.
- Never try new things in the last few days: As the chemistry syllabus is quite vast, so you must prepare for it only up to the extent where you do not start forgetting the old things. 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. As the chemistry syllabus is vast and especially inorganic chemistry this may look like a mammoth task, but with right practice, you can easily do the same.
- 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. Maintain a healthy balanced diet and avoid overly rich food, oily, and leftovers, as they can upset your stomach. Best to eat small meals at regular intervals to keep your mind fresh.
Identify the best books suiting your study style and work with them at regular intervals, so that you are able to master the syllabus in the due course of time.
MCQs for NEET chemistry are generally not very difficult, except with a few exceptions. Students must stick to the time management formulae in order to perform best within the stipulated time period. Some good books to prepare for NEET chemistry syllabus are as follows:
