Hello All,

After going through this forum, I thought there could be enough help on this line. "ISB only gives provisional admission based on CAT. If given admission you will have to clear GMAT with a minimum score of 690-source rediff.com", Got just curious on this sentence.

Im still an aspirant of ISB, not a scorer yet. I would reach 4 and half years of experience in IT by the time I give CAT this year i.e 2007.

Firstly, is this the right time for me to opt for ISB? If so, how is it possible from this end? Also what special skills would ISB looking for?

In Short what are do's and don'ts from this end
