Answer: -I feel/believe I would pay the $150 on time or before. For instance if it was a credit card you should pay as soon as you get the statement or at least 12 days before it is due.If it is a loan a straight simple loan and you only get charge on what is owed and there is no penalty for early payoff i would do option 2 most definitely. -As long as you are making the mininum payment. it won't matter how you pay it. Paying it off at once saves u interest charges which is probably the best way to do this. -If you are trying to improve your credit score, all those extra payments won't help at all. You can improve your score by paying down your credit card balances below 30%. Best way is to concentrate on the highest interest rate card, while making minimum payments on the rest. When the highest rate card is paid off, move to the next till they are paid off.After you pay off credit card debt, negotiate settlement of any negatives on your credit .A consistent on time payment history is the best way to improve your credit.
