for better understanding organic chemistry one must study general organic chemistry[base of organic chemistry] very well.because in this topic all types of organic reactions and their reaction mechanisms and types of organic reagents and reaction intermediates are explained very well.which are used in whole organic chemistry again and again.one must understand mechanisms confidently because most of questions are based on mechanisms specially name reactions .in physical one must learn formulas[just like physics] and concepts then solve more and questions to develop concepts on tips.
for inorganic chemistry you have to learn periodic table well.and properties of elements of all groups .
questions from d &f block elements and co-ordination compounds are often asked in exams.
