OG probability [#permalink] New post 19 Feb 2012, 08:18
Hi All

The probability questions in OG are fairly easy ..
Could some one guide me if one should be doing tougher problems than those given in OG if you are tragetting 700+ or will OG suffice.
I am practising both 12th edition and 10th edition !

Thank you in advance.
best regards
