dont pay interest for credit card. pay  dues in time if u can pay in full.

spend as much as you can but dont cross the limit.

dont apply for  a lot of credit cards. wait until you are offered for one.

dont accept first or second offer. they will offer you a better card each time if u continue ignoring their offer.

to see a free copy of your report use any one of the credit reporting agency website but dont forget to  terminate before the trial peroid ends.
