so i don't have the greatest credit in the world.. i was told to make a credit karma account.. so i did, so that i could work on getting my credit in better shape so that maybe down the line that i could purchase a home or a car or something in the long of those lines.. so my credit score according to credit karma is 588 my vantage is 600 which i'm guessing is like a median of all three credit bureaus? (correct me if i'm wrong) well anyways it said that i could apply for a credit card or get a pre approval for one without my credit being affected and according to the credit card's denial my credit score is 178? how is that possible then afterwards i googled how i could get all of my credit scores(you have to pay for most of these) or "credit reports". so i couldn't see the credit scores for each one but none of my credit reports listed enough in my opinion where my credit score would be 178? do credit cards have their own credit thing? i'm so confused and lost. i'm trying to get an apartment..(which they do rent to people with not so great credit) but, i don't want to have to pay 3 months extra in security deposit because creditkarma is giving me false information about my credit.
