Alright well I'm a freshman in college and have been applying to several credit cards. I would like to have very good credit so that when I apply for loans it will help out. I don't know anything about loans or credit cards or how that process goes, but logically I'm thinking that it would benefit me to have a excellent credit score. Anyways, I've applied to about 4 credit cards and most are accepting me since I have a 'thin file' or basically no credit history. Is it okay to open up that many credit cards. I will only probably be spending 30$ on each one a month and paying it off immediately. I don't plan on doing anything than buying lunch and stuff of that sort here and there w/ my credit cards. Also if anyone has tips on how to increase my credit score in a quick way feel free to give me advice. It's much appreciated. Thanks!
