Read about my passion for student credit cards
If you absolutely must exceed your limit, do everything in your power to pay back until you are under your limit as soon as possible. Many credit card companies will let you go over your limit, but the interest rates they will charge you will be exorbitant, and the fact that you exceeded your balance may be reflected in your credit report. Another essential step is always paying all of your bills on time. This includes your rent and utility bills as well as your student credit card bills. Creditors pay close attention to whether you have been late with your payments, and any bill that is late by a certain time period (usually 30 days) appears in your credit report as another note that will drop your credit rating ever further.
