> Letter grades from A - F would be a good idea. Their meaning and use has been ingrained since childhood.
In many countries A - F grading system is not commonly used. For example in the country where I was born they use 1 - 5 grading system and A - F means nothing. I think rating with stars is much more widespread and would be wiser choice for any project with global ambitions.
