Easiest way to have a user select a letter grade?

Question

I have a report card form that I'm creating for customers to rate performance in several areas. Our old format was using radio buttons, each labeled A-F with one N/A option. The current idea from marketing is to just have users input the letter grade in a text field.

I'm thinking that there's a more simple intuitive way to present this kind of data, but I'm having trouble finding any ideas. Perhaps I'm searching for the wrong thing. I was considering using a fixed unit slider and displaying the letter grade next to it. I don't think that management would be too keen on changing the rating unit either (no 5 stars or anything). Any great methods out there?

If you have enough room, six radio buttons have the advantage that all the options are clearly laid out all the time. One can be selected with a single mouse click. The selected option, and all the alternatives remain visible.

Assuming that you don't have enough space for this luxury, then next best will be a pull-down pick list. This takes only the space to display the one selected grade. The down-arrow is a visual clue to bring up the list of options. Since you have only 6 options selection of one is quick, familiar to all users, and easier than having to type a key from the keyboard. Done correctly, a user pressing the associated key will also select from the list, so the user can either type the grade, or use the pull down, whichever they prefer.
