<prompt> Human: Hi everyone. I am a 19 year old full-time college student working full-time between three jobs. I wanted to start building my credit currently 629 so that I could get an apartment next year. So, I decided to apply for a Discover Student card - it sounded great especially with the good grades incentive. Unfortunately, my campus wi-fi went down while I was trying to approve the final step. I tried to restart my application but I was told it was already submitted. I received an e-mail a couple hours later saying that my CC request had been declined, so I ended up applying for a Capital One Journey student card - I was approved for 300 credit. Sounded great!This morning I got an e-mail saying that my Discover card was in fact on the way. I called Discover and was told that the hiccup in my system caused them to still process my application further and that I actually was approved for the Discover student card with a 500 credit line. Now Im not really sure what to do. I think that the Discover card is much better because of its rewards and higher limit and dont know if I should just keep both cards and create low balances on both of them or cancel the Capital One card. Would it hurt my credit score to cancel the Capital One card before its been used?Thanks in advance for your help!  <response>: No reason not to keep both, as there are no annual fees. Pay both in full every month and in a year or so try getting a card with good rewards.
