i was curious to see what my credit score was so i checked on myfico.com. i noticed that there was an error on my report - it stated that i had something in collections but this bill had been paid in full prior to this account going into collections. i was able to send disputes to transunion, experian and equifax - transunion was able to delete the collections notation on my report. i checked my credit score on transunion and it showed 678 but on myfico.com it showed my score at 654. why is there such a huge difference between myfico.com and the credit bureaus' website? shouldn't it be somewhat similar?
