A few other points of consideration.

How much to you anticipate spending on the card each month? Most miles cards have annual fees, and if you're only spending a few hundred a month, the miles earned won't be worth as much as the fee is costing you.

Second, miles cards typically have high interest rates, so a good rule of thumb is to only use it for purchases you will pay off in full every month. Don't carry a balance on a high interest miles card. It's also worth mentioning that many college students get themselves into bad debt by over-spending when they get their first card. Don't fall into that trap.
