Dear Aspirant,

you are said that you are currently 12th ARTS and you are aspiring for Govt Jobs and you aiming to write after the 12th studies for Government jobs well, go with SSC CHSL as they are well organized and comes with calendar every year there will be certain clarity, but when you compare RRB it's some times a Herculean task because there you can't expect a calendar for recruitment and things not work well, with SSC CHSL its a better option for you with 12th.
