For Banking Examinations be it Po , Clerical , Specialist Officer , Management trainee :
Complete R.S. Aggarwal chapter on Series only ( If U have time solve both the exercises , approx 1100 problems thoroughly , if time is less go thru only the first exercise ) , because problems which come in banking Papers are always from this book and this chapter.However if you are trying for SSC , AAO or other exams then you have to go thru the entire Non-Verbal Section.
Non - Verbal Reasoning may seem boring initially , but trust me , by the time you solve 100 - 150 Problems , U will find it the most Interesting Part and U will realise the fact that it is the most scoring part of the reasoning section.
