credit score?

I need to raise my credit score 20-30 points in the next 30 to 60 days. I have two good revolving accounts with no late payments…I also I have a few accounts in collections ranging from 12 to 48 months old. I am being told different things…if I take care of the collections account then it would rate me highier and also being told if I pay them off it will show recent history and it could lower my score…please help trying to refinance my house
