 Read instructions carefully and avoid haste.
 Stating observation does not mean identifying the substance.
 Learn all equations with the relevant conditions. If acids are used, remember to state the concentration.
 Pay attention to details during practical work and focus on both observations and inferences.
 Learn the various terms, get to know IUPAC Nomenclature well and ensure structural formulae are represented correctly.
 Exposure to variety of numericals is essential and habit of step wise working will fetch rich dividends.
 Focus on the colours of precipitates and their solubilities in reagents such as NaOH, NH4OH.
 Solubilities of salts and properties of salts require special attention to understand the methods of preparation of salts.
 Knowledge of various types of oxides essential with relevant examples.
 Learn the laws, principles and definitions verbatim.
 Learn the tests for identifying the cations and anions and the related observations.
 Tabulate Industrial preparations and make a comparative study of the details.
 Study alloys in tabulated form highlighting the main component and the other metals and their special properties.
 Remember the rules for selective discharge of ions and learn to apply them.
 Various roles of different substances used must be understood in metallurgy.
 Ensure all aspects of the syllabus are covered and avoid selective study.
 Practice solving previous year’s Question Papers to get an insight into the pattern of the papers.
