Dear Bankersdaily Aspirants,

IBPS RRB PO & Office Assistant 2018 Preliminary Examination starts from 11th August, 2018. The IBPS RRB Exam 2018 is one of the most expected exam of the year. The reason for the consummate expectation is different from that of the others.

The number of candidates attending the IBPS RRB PO & Office Assistant is high when compared to the other exams like SBI & Insurance Exams. The other important factor is that , no English section is there in the preliminary examination of the IBPS RRB PO & Assistant Exams.
