Hello arjun,

Most probably first exam is of Aptitude, General Awareness, Basic Mathematics(No hard calculus) and most important English. 1.Aptitude: R S Agrawal, I haven't really studied it but my friends here thinks so.So, It depends on your current aptitude level. If you can solve SSC-CHSL level aptitude you can crack it too.
