Prep tip

Physical chemistry numericals (solutions, electrochemistry, kinetics) are steady marks: write the formula, substitute with units and round sensibly. In organic chemistry, learn the named reactions with reagents and conditions, and the conversions between functional groups. Learn each d-block trend with one reason.

Suggested order: Unit I, then II, then III, then IV, then V, then VI, then VII, then VIII, then IX, and X last.
