This is how you can start(you can study from the study material of the institute instead of referring any other book in the beginning)
ACCOUNTS - start with partnership accounts as it is quite familiar chapter and you will be able to solve the questions of first two units after reading and understanding the theory part as well as recollecting whatever you have learnt in 12th .
LAW - It is not a difficult subject. You can start with any chapter though starting with Indian contract act would be the best option.
AUDITING- Start from the first chapter as this will make you concepts clear and you will not face any difficulty in the chapters to come.
TAXATION - You can start with service tax and VAT part first.
COST ACCOUNTING- Read the first chapter which is a theory chapter and tells about the basics of cost accounting after reading this chapter you can proceed to other chapters .
FINANCIAL MANAGEMENT - same as above
INFORMATION PRACTICE - You can start with any chapter .Internet and networking are important chapters so you may just go through them.
