Hello Aspirant,

You are not late at all because IBPS RRB offer different posts which have different age eligibilty so for a post of Office Assistant maximum age limit is 28 years whereas for Officer Scale-III it is 40 years. So you have enough time to prepare for it until your graduation completes because in oreder to apply for IBPS RRB you must have degree of graduation.

What to do if you are weak in calculations!! No need to worry just focus the areas in which you are weak and try to do it a much as possible until it seems easy to you because hardwork is the only key to success.
