NEET Syllabus for Chemistry
NEET is a common test for admission to MBBS & BDS courses in medical Universities of India. To score high in the exam a candidate should be aware of NEET Syllabus. The NEET UG Syllabus is recommended by the Medical Council of India (MCI). It includes Physics, Chemistry & Biology sections, which is prepared after reviewing various State syllabi as well as the Central Board of Secondary Education (CBSE), Council Board of School Education (COBSE) and National Council of Education Research and Training (NCERT).
