The percentage is easy:

precentage = 100*number_correct/14

Mapping the letter grades to percentages is going to require someone
*deciding* what grade gets what range of percentages. There's no fixed
equivalance. 

Heck, back in the 1960s, my 5th grade teacher had a sort of sliding
window and chart gizmo that would assign the grades according to how
many students got answers right (ie grading on the curve) 

So an A didn't just depend on how many you got right. It depended on
how well the rest of the class did too.
