okay. Get the First lessons in Financial Reporting book of M P Vijay kumar, as this book will help you to understand the concepts and help you in how to approach the practical sums. once done with the book try ICAI SM sums it will be a good revision for you. next for Accounting Standards go with ICAI SM book since in exam, problems comes from that book only. once all this is done try RTPs SA of past years this will give you the grip you need for exams
Rest of all Confidence And Motivation is at most important.
