<prompt> Human: I am a 21 year old college student. Shortly after i turned 21 i decided it would be wise if i got a credit card to build credit and get a higher credit score. I got approved for a capital one card first and didnt fill out the final form, and then i got approved for a discover card so i filled out the information. i didnt think i was going to get the capital one card and i got my discover card and have been very happy with it. shortly after i got my discover card i got a capital one card in the mail and at that point i thought since i have it i might as well keep it. i later found there is a 40 annual fee on it. I currently dont have a balance on the capital one cardand havent had a balance for 4 months. I keep my balance under 25 of my credit limit for my discover card. I havent missed a payment, i got my FICO credit score which i thought was pretty good of 726.Im fairly certain i will cancel my capital one card due to the annual fee. I was wondering what that will do to my credit score and If i should do it. Also, is there anything i should know about canceling my card, any thing i need to say or do to ensure that it goes smoothly.  <response>: Can you call customer service and have them do a product change to a Capital One card that has no annual fee? If not, then I would just cancel.You can expect to see your credit take a brief dip after closing the Cap1 card. But your score will recover quickly over time.
