Because as we know in banking exams we usually face timing issues so here we will start to speed up our calculation ability.. In which we will study about the calculation tricks for example if you calculate any number with 99 so how could we do this we can't do as we were doing in the primary school or in the school time so here what we will do we will do 100 - 1 which will be multiplied by that number so it would be very easy to calculate and in addition I would say number of two digit multiplication we will learn everything about mathematics which comes in the IBPS exams and further I will discuss about the the HCF and LCM time work and simplification and many more topics
