1. Low-interest rate: Ideally, you should pay the entire balance on your card every month so you don’t accrue any interest charges. But just in case you do need to carry a balance over to the next month, you can minimize the amount of interest you’re charged by choosing a card with a low APR. Currently, the >average student credit card APR is 13.14 percent. Keep in mind that as a college student without much credit history, you might not be able to qualify for the lowest rates. However, the APR is a good comparison point when you evaluate different offers.
