Preparation Tips 

Candidates can prepare for practice papers and mock tests of previous year exams.

Candidates can prepare their revision notes to get a better understanding of all the topics.

Along with NCERT books candidates must refer some other books that give you space for practice.

As inorganic chemistry has a vast syllabus and difficult structural diagrams, best to practice them regularly.

Candidates have to practise managing their time. They have to do previous year papers so that they can make proper timings for all types of sections which will give a boost in managing their timings during the exam.

Candidates have to divide the exam into high-priority, medium-priority, and low-priority so that they can prepare more for high importance questions.

 

Frequently Asked Questions 

1. What is the weightage of class 11th and class 12th syllabus in NEET Chemistry syllabus?

There is no such specific number to denote the weightage of class 11th and class 12th NEET Chemistry syllabus. According to some subject experts, class 12th holds a slightly higher weightage than class 11th.

2. Is it necessary to give mock tests before appearing for the NEET exam?

Mock tests are very helpful to score outstanding marks in NEET 2023. Students must give mock tests like a real exam. This will speed up the accuracy and concepts and help manage the time while taking the real NEET exam.

3. Which books are the best to prepare for the NEET Chemistry syllabus?

NCERT books contain all the topics and concepts that are important for the NEET 2023 exam. Therefore, students must thoroughly go through chapters and revise every concept before the NEET exam.
