Organic Chemistry:

For the conversion reactions in organic chemistry.

Try to understand the mechanism of the reactions.

There are specific mechanisms for the reactions and they are somehow related too. For example if one has understood the types of nucleophilic substitution reactions S_N1 and S_N2 then any type of substitution with any reactant can be handled.

To get good hold on the conversations, you must remember the main chemical reactions and the synthesis of compounds like carbonyls, acids, amines etc.

Do remember simple steps of preparations of compounds, and yes basic name reactions like aldol reaction helps a lot .

Practice the equations by forming the product and then again forming the reactants from products, one must learn both the conditions so that at any step of conversion you are able to attempt it easily.

InOrganic Chemistry:

The periodic table is the fundamental base to study the position and properties of elements. Prepare a concept map which will help in understanding the trends in properties.

Try to understand the metallurgical operations and where they are applied. Please don’t memorise or mug up.

Balance you chemical reactions and practice the formula will be the best technique to understand and memorise formulas.

Coordination compounds require problem solving practice and one can score well in sub-topic like isomerism.
