I'm just wondering what chargable expenses you have as a college student that total $450 a month. It sounds like you are determined to charge that 20% even if you need to or not, because you think it will boost your scores.
Running up 20% of the limit and paying it off every month won't help you build credit any faster than just using it for food and groceries. If you are never carrying a balance, the amount on your credit report is likely not going to be zero, but not going to be whatever your max balance is either as the reporting schedules are likely not lined up. So, I think you are much better off just using the card for one category of recurring purchases (gas, groceries) than TRYING to run up a certain balance. Again: if you are not carrying a balance, the amount you charge in a given month won't greatly affect your score. Occasional use and paying a full balance will boost your scores over time, regardless of how much you are charging. So, don't go out and try to buy yourself a higher credit score.
As for cash back, be careful. It can be a great reward. But, studies have shown people spend up to 10% more with a cash back credit report than they would paying cash, because they are so motivated by getting the "cash back". At that point, you are just overspending, not earning anything!
