Chemistry rewards thorough NCERT preparation more than any other NEET subject — roughly 85% of Inorganic and Organic questions are quoted near-verbatim from NCERT. Physical Chemistry is more numerical and overlaps significantly with JEE prep. Average toppers attempt 42–44 of 45 Chemistry questions and score 160+. The weakest area for most students is Organic reaction mechanisms.
