We have started the 56 days Study Plan for IBPS PO Prelims. This study plan is to efficiently utilise time and hard work to channelise it towards smart work. From now quizzes on Bankersadda will be according to the given study plan and this will help you prepare important topics in limited time.

Today is DAY 38 of the study plan and in Quantitative Aptitude today’s chapter is Practice of 8-10 Chapters (Time & Distance And Boat & Streams)
