When will I get a credit increase?
I got an increase about a year after I received my capital one card.  And the sad thing is you can't just call and ask for one because they don't do it.  So all you have to do is keep paying on time.  Keep your balance relatively medium-ish - eventually they will increase it without you knowing.  The plus side to waiting is that you DON't hav the higher limit.  LOL.
their is no easy way.\nif u wanna improve in something that means ur gonna have to work hard for it.\nso its studying hard or not passing the class.
