NEET Exam Classwise Chemistry Syllabus PDF Download

The NEET Chemistry section is generally considered to be a high-scoring section due to the fact that questions are based on the fundamental concepts from class 11 and class 12, such as chemical reactions, mechanisms, compositions and chain reactions. The questions in this section are mainly taken from NCERT textbooks and the previous year's exams have shown that the pattern of questions is the same, just with different levels of difficulty.
