I’ve just paid my last card debt!!!! So now, main things to pay all my bills on time and to exclude new debts. I am strongly going to build positive credit history and want to ask my mum to be a co-signer. So I will get good credit card with good features therefore good points in my credit report. But I haven’t decided what card to choose. I am thinking about Amex blue cash or Discover Platinum. They are pretty good.
