<prompt> Human: I am a university student who makes most of my extra money through small jobs that pay cash. Im unemployed Ive heard that having a credit card and just paying it off in full is a good way to build credit, but Ive also heard that since I have student loans out already that I shouldnt get one. I currently use a debit card from a small FCU that Ive had for around 5 years Im now 19, and my dad was on my account until I turned 18 and have never had an issue managing money. Should I get a credit card? If so, are there any suggestions on what card to get for a student in California?  <response>: Good job managing money. Yes, Discover has a good student card that gives a small cash reward for getting good grades, and it would be good for you to start building a credit history.
