I read that and I don't know if this is actually possible. I feel like there are factors in this that were overlooked. Everything I read prior to this said it takes at least 3 months to see a noticeable raise in points.
Looking over the article, I would say yes it is but you have to consider that you won't have the same credit cards or same debt so you can't expect to achieve this exactly. I think it is reasonable to aim for 50 in 3 months time.
You can raise your score in a week's time but this all depends on many different factor's. It depends on how quick things are filed, adjusted, what kind of credit it is, what other debts may or may not be involved. You can be in debt to the same bank through 3 different credit cards and not even know it because a collection agency is handling the debt.
